That explains the changes Google did to the Timeline and why you can't see it in the browser anymore. That is great from them actually.
By stopping that one specific way they supported warrantless surveillance, Google probably managed to make the current round of litigation moot so that Google won't suffer a negative ruling on the merits. They can start all over again in a slightly different way once the attention goes down a bit.
Google moved to finally address this after the press started focusing on how hording location data could put women who visited reproductive healthcare clinics in legal jeopardy.

I dislike Google as much as the next guy, but, regardless of its intentions in making Chrome and Android open source and secure, it has a huge positive impact on privacy and human rights.
The purpose of a thing is what it does - android and chrome and everything else Google does serves to maintain or extend their control over the value and flow of user data.
Android and Chrome are net negatives. Google subsumed Firefox, made Mozilla beholden to them, derailed their viability as a competitor to chrome, poached talent, manipulated user exposure, degraded performance targeting competitors, and otherwise engaged in ruthless corporate fuckery to get where they are, with near absolute dominance of the browser market. Android is touted as an alternative to Apple, but they just as enthusiastically build up walled gardens, abuse consumer trust, play into monopolistic market dynamics, empower ISPs and others to force a "you actually rent your device" type model on consumers, and otherwise maximize the amount of money extracted per user without any concurrent return in value.
The internet, smartphones, and browsers are a dystopian, cynical abomination, and if there's any justice in the universe, AI will result in the total dissolution of giant tech companies like Google, and there will be a future free of institutions like it.
Don't hate the player, hate the game.
See https://www.eff.org/deeplinks/2025/04/eff-congress-heres-wha... or probably any recent publication about privacy rights by the eff.
Like I get it but be mad that congress is a bunch of goofy old people who give zero shits. If you can point at some lobbying by google then by all means so be it - certainly they appeared to have kissed the ring as of late. But keep in mind googlers personally direct money into the eff every year too.
They were trying really really hard to do the right thing. Lots of people really cared about it, many to the point of it being detrimental to just making the product better.
I don't get it. In the first sentence you're claiming that there's "basically no obligation to individual consumers", but when they do a pro-consumer thing, you dismiss it as being "made to cover their own ass". Which one is it? Is this just a lot of words to say that Google isn't as pro-consumer as you'd like it to be?
The truth is probably somewhere in between if you were to actually sit down and talk with all the people involved with such a decision.
Regardless of the reasons though I do think we should give praise to companies and organizations doing things that ultimately benefit us though. We should give feedback as to the changes we like to let decision-makers know people actually do care.
I think it is appropriate to judge their actions, but I am not sure any simplistic “good motives/bad motives“ discussion can be fruitful.
One can cause the other, but the burden of proof is on the claimant that wrecking a mass-produced special purpose autonomous vehicle did more tangible harm to a human being than make some engineer sad before they rolled up their sleeves and built a replacement.
The Waymo emphatically did not care it was destroyed.
Should I be legally allowed to assault you or vandalize your property because I think your political orientation or that of your company is not "on the right side of history" ?
The opposite of dragnet surveillance, which is what flock and geofencing warrants are: data aggregated and shared without the consent of the user, is data collection minimization even when done for security or apps.
Worth noting that 6G MIMO beamforming requires being able to calculate incredibly accurate location information in order to tune the signal towards your device. I don't know enough to be able to speak more in depth about this, but my guess would be that the adage of cell AP based aGPS is likely to be able to surface far more accurate device location than before.
Incredible
My knowledge in this topic is not deep, but cell precision should be pretty accurate, because modern cell tower areas are much smaller, then to have well tuned beamformer it need to have relative precise angles between antennas and know signal travel time (distance). I think it should achieve something 30 or 15 meter precision (doing assumption that distance is accurate in 50/100ns order)
I disagree that they need my location data. I am perfectly capable of telling them the location where I want a pick-up, and they are perfectly capable of imposing penalties if I incorrectly report it. Just like happened with cabs in the old days, who were somehow able to pick me up without real-time location tracking.
(Not to say that you shouldn't be able to just turn on location tracking if that's what you want to do, but there's no reason that they can't function without it.)
Most people are like me: they don't care about being protected from the courts, because the courts don't pose risk to them, and as a matter of statistical fact, they are correct.
You see, the cops had a murder in a remote place. They got a warrant, and the warrant showed 12 people in and out of a small area near the murder, of which one phone went there many times.
They got another warrant, for that one phone, and traced it back to someone who is obviously the murderer. The courts decided to suppress this, never mind the cops got warrants at both steps, and their investigation was as minimally invasive as one could imagine for this sort of thing.
So it's not unreasonable to wonder just what we're protecting sometimes, as I understand that while the decision here doesn't technically ban all geofence warrants, it makes them nearly impossible as a practical matter.
One can read the decision here:

Honestly, do you look at the justice system in the United States and think "You know the real issue here is that not enough people are being punished"?
It sure would have been useful for governments in the South to grab the location data of enslaved people trying to escape—would they, like the average user today, have known to turn off these settings?
It's great for Texas to buy data from brokers about women trying to access reproductive healthcare across state lines from apps carelessly sharing it. The courts don't pose a risk to you until the law changes and suddenly they do.
This is about the government getting data through a loophole that violates the 4th amendment—the difference between a society that collects everything and presumes guilt, and one that targets specific people when they're suspected of a specific crime.
To be clear, no disagreement with your self-risk-assessment, and reasonable people can disagree on where their paranoia threshold is.
The US's protections are rooted in observations of local authority (and Crown-backed authority) trying to disrupt what the revolutionaries self-observed to be peaceful demonstrations, peaceful entry of thought into the public discourse, and public discourse itself. It's grounded in Enlightenment-era belief that unsuppressed discourse is the best path to real truths, and respect for real truths via the distributed, democratic comprehension of them are the foundation of good governance and good society.
Germany watched a significantly post-Enlightenment, free, democratic people talk its way from democracy straight into fascism, and concluded that some kinds of discourse are so toxic to the actual practice of discovery of the aforementioned truths that they are to be excluded from the public sphere.
Both cultures came by their conclusions honestly and there's some merit to both points of view.
One justice asked petitioner that because 'If you don't want the government to have your location history, you just flip that off. You dont have to have that feature on your phone. so whats the issue?'
They continue to talk about the Terms of Service stating that Google will comply with legitimate government requests. And both the petitioner and justices seem to agree that ANY data would be then up for grabs by the government (without a warrant) if it is stored in the cloud (including email, docs, photos, calendar, business records, etc). Sotomayor points out that the government would need NO warrant to access these records.
The google feature doesn't exist anymore. But in the amicus brief some 30 providers still have features in similar pattern of record storage. 'Google can track you down to 3 feet'. Google had to search "500 million" accounts for the search in question.
Justice Jackson asks why they aren't looking at the case as a 'reasonable expectation of privacy'? The petitioner agrees, and points out that the data is protected by a password. So the data is NOT public.
"Data on the network is property." - how we get laws against stealing data/trespassing data
Probable Cause was an interesting argument. about 90 minutes in. It went by too quickly. The justice seems to say that google's servers are one 'place'. The justice also sees the output of 3 people despite google 'searching' 19 people as the only people who matter.
Responder is leaning heavy into the 'consent' for google to store location history. Is it possible to turn location history off on modern android phones? Responder also argues that because you're in public AT SOME POINT, then your location data is no different than a cctv data pointing at the street. Then a justice interrupts to make the responder say that YES the government CAN perform these searches on anyone it wants any time it wants without a warrant. For example people who seek abortion, or were at a political event. And the responder agrees!
Responder says the email, photos, and docs still need a warrant because they're like your thoughts or mail, where location is different because people are 'constantly advertising' their location to google.
To me, the responder is arguing two things:
1. That whatever you do in public is always available without a warrant
2. Your location history stored in google (or others) are generated in public and are therefore don't require a warrant.
Responder says location records are records google creates on your phone. Justice asks why no one of the 500M people who were searched have complained? (idk, maybe because we have no way of knowing we were searched?)
> https://www.cbsnews.com/news/google-location-tracking-data-w...
Can someone catch me up on how the settlement against Google where turning off location on your phone didn't stop them from collecting location data, plays in this Supreme Court case?
Isn't this like cell tower data, where the user doesn't have a choice if their location data is collected?
Is your location history
A) a bank record (less protected), or
B) a "digital diary" (strongly protected) ?
You must have misheard this as this is not true country wide (see US v Warshak) and in practice the government treats these as needing a warrant because of that and the time requirement in the Stored Communications Act (and any major provider will explicitly refuse handing over content data without a warrant).
Gorsuch in particular thinks the Third Party Doctrine is bullshit and is happy to write that down (like in Carpenter) and today seemed to be trotting that out again (though I only read the beginning of arguments).
Later the same question was put to the government, and they admitted the same: under the government's theory a warrant would not be needed.
> Later the same question was put to the government, and they admitted the same: under the government's theory a warrant would not be needed.
You said the opposite:
> Responder says the email, photos, and docs still need a warrant because they're like your thoughts or mail
From Orin Kerr's live tweets (Feigin for DOJ, Unikowsky for Chatrie) of what I believe you were summarizing there:
> Barrett: I'm concerned with your position being maximalist, too. Calendars, photos, email. And monitoring of homes. Are you conceding this would be a search?
> Feigin: Warrant is needed for calendars, photos, email. [OK comments: Virtual lockers]. Not conceding homes.
...
> Finally, Unikowksy rebuttal: We welcome the government's concession as to calendars, photos. But I don't understand how they distinguish that from this.

That's not relevant to this case.
Suppose I'm traveling in the back of a van with blacked windows. Nobody can see me. No camera in the world will record me. They are arguing that I still have no expectation of privacy, which is ridiculous. Maybe if you are walking around with your face visible, sure, but that's a important condition.
Another problem with this argument is facial recognition is far from perfect.
So a large apartment tower housing, I dunno, thousands, of families can entirely be searched because it's just "one place"? Chances are this even multiple buildings, so really more like a whole apartment complex. Sorry, someone in building 56 was maybe selling drugs, we're here to dig through your wardrobe even though you're in building 12 half a block away..."
They might as well apply for warrants as "Sol 3, Earth".
With cameras going up everywhere, operated by the government and with AI enabled, I wonder if geofencing is the biggest privacy threat we have.
There's a cynical joke in the refrigeration/hvac industry to the tune of "it's good for the environment as long as DuPont has a monopoly on it/the 3rd world isn't making it" in reference to refrigerants' reliable pattern of being identified as bad for the environment and get regulated away right as patents expire, manufacturing proliferates and they and the equipment that uses them become cheap.
Geofencing warrants and cell location data collection give me the same sort of "they're getting rid of it to move onto the next thing" vibes. Not that we shouldn't get rid of it.
Another would be incentives. There's no reason to collect cell location data for everyone if you aren't able to use it for anything. I think just the fact that we are all monitored constantly is its own violation of our rights. We should have laws banning these practices.
"The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."
As relevant here, there's two pieces. The threshold requirement is some sort of ownership. The right exists with respect to "their persons, houses, papers, and effects." Assuming digital data constitutes "papers," the accused has to show that it's "their" papers. The hypothetical you're responding to compares the bank's camera footage with the cell phone company's location information. Those seem indistinguishable for that prong.
You have a reasonable argument that "scope" and "incentives" are relevant to the second prong of what's "unreasonable." But you don't get there if you don't get past the first prong, right?
The law as written provides the rules of the game. Nobody should get to cheat, not the government, not a citizen, not a business, just because someone can plausibly argue that if the law were rewritten today it'd be written differently.
If the claim is true that the law would be and should be written differently today, then: Rewrite. The. Law.
If you don't have enough public support for that, then you have no business imposing your view on your fellow citizens. If you do have enough public support, but Congress is being dysfunctional (this is usually the case today), then communicate with your congresspeople and/or try vote them out, and persuade your fellow citizens to do the same. Don't cheat at the game. Play it.
If we don't want the government to be able to do that, we should pass laws to that effect.
Though again, making no judgment as to whether or not it should be allowed. I just think it should be a law, and not casting modern values on the 1700s era founders' words.
I'm also pretty sure they would be 100% horrified by what it has become.
So yes, it should be law. The US supreme court however does not make laws (or at least, they shouldn't be), they interpret the constitution. And the US constitution is well overdue for a more tech aware version, it's just that with the lawmakers apparently in the pockets of the tech billionaires I think that the chances of such an overhaul approach zero.
I suspect you're right--a bunch of high-IQ libertarian men who had just overthrown their government would write the 4th amendment differently if confronted with universal digital surveillance. But is that how we decide the legal effect of the constitution? We're stuck not only with what the founders actually wrote, but what they would have written if confronted with modern facts?
What are the parameters of this analysis? Do we assume the same James Madison--we have transported him into present day with his knowledge and thought processes intact and are simply presenting him with additional facts? Or do we assume a modern James Madison--the same kind of person today that James Madison was back then. And who decides what reincarnated James Madison would or would not have done--and why do we trust that this medium is correct?
I think it's simpler to say that the meaning of the constitution ends at what is written. What the founders intended is relevant to the extent we're trying to figure out what what they meant, at the time, by the words they used. But we won't go so far as to speculate about what the founders would have written if confronted with modern facts. We have people who can decide what to do about modern facts: they're called voters.
This is a bit of a specious argument, though, since of course what they wrote often didn't clearly articulate what they necessarily meant. You even point this out above: what is ownership, and what is unreasonable? Does entrusting your effects to a third party for safe keeping make them less your effects, etc.
Sure. But what "they necessarily meant by the words they said" is different from "what they would have said if confronted with different facts."
The ownership issue is a good example. Does the word "their ... papers and effects" include third-party data about someone? Third-party data existed in 1789. British people love record-keeping, and the founders were sophisticated people with lawyers, accountants, merchant accounts, etc. If the fourth amendment meant to include third-party information about someone, the founders wouldn't have used the ownership language that they used.
So the real argument is that, if the founders saw how important and sensitive third-party information is today, they would have included it. They wouldn't have used the ownership language they used. That's quite a different argument! It's not just trying to understand what people meant by the words they used. It's trying to reanimate them and ask them questions to scenarios they never contemplated.
So the plaintiffs in this case are trying to get the dead hand of the founders to smack the police and the judge. They're the ones invoking "sacred texts" written 237 years ago by a bunch of old white guys to ask the Supreme Court to overrule what police in Virginia did pursuant to Virginia law.
Your post raises the question: who is the "we" you're referring to--the "we" who is empowered to "adjust the laws?" Who is empowered to decide whether circumstances have, in fact, changed? And if there has been a change--which way do those changes cut? Surely it's the current voters of Virginia who get to make that decision, right?
But the Supremacy Clause says the Constitution overrides Virginia law.
If we decide the Fourth Amendment applies here, Virginia law loses.
Yes, but the only way to do that is to say that the dead hand of the founders overrules current Virginia law. The plaintiffs want James Madison from his grave to impose restrictions on the police that voters in Virginia in 2026 have declined to impose.
Virginia voters similarly can’t legalize slavery or ban the New York Times. The age of the restriction is irrelevant.
Not according to the comment I was responding to: "Has anything changed since the sacred texts were written or we just going to keep acting as though we can never adjust the laws."
Things can change in a way that's covered by the Constitution. Say, technology that makes Fourth Amendment violations easier to do; still potentially covered!
Things can change in a way that's not covered by the Constitution. Now you need an amendment.
The Fourth Amendment is quite broad and can thus handle all sorts of change.
> Has anything changed since the sacred texts were written or we just going to keep acting as though we can never adjust the laws
... the answer is "Oh boy, Chatrie sure does hope nothing has changed, and the Founders would have hated geofencing had they had any way to know what it was! Otherwise, the laws passed in the past 50 years say it's legal and fine."
Debating who the "we" is is losing the forest for the trees--we're wading into a conversation debating the power of a state or local municipality instead of looking at the actual issue where the federal government isn't protecting is citizens because "technically the slaveowners didn't say cell phone in their document".
I'd like it to be otherwise, but this Court has demonstrated in its overturning of Roe v. Wade that the risk of leaving it up to SCOTUS to synthesize "prenumbrae" and rights to privacy (which would have not been a thing anyone would have written in the 1700s) is that reasonable people can disagree on what those things are, unless you write them down explicitly in the document that requires a lot of effort to change.
Given the ubiquity of security cameras they can just canvas local businesses and ask them to give it up. Given that warrants are involved, they can't even refuse.
Sometimes a business will challenge a court order if it’s about their own customers, employees, owners, or business dealings. The information requested should be relevant to the investigation, minimal to be helpful, and create as little burden on the business as is practical.
Also, if you’re not the subject of the investigation it’s often a subpoena rather than a warrant. There are major differences between these types of order in the US. A subpoena is an order to produce the evidence. A warrant is an order that allows law enforcement to seize it, using force if needed. As someone who has dealt with law enforcement requests for business data about customers quite a bit in the past, it’s often a simple request first and a subpoena otherwise.
This is the disaggregation of power of surveillance.
Outdoor cameras around a bank, and license plates both have their own justifications. Outdoor cameras surveillance is in an area with no reasonable expectation of privacy. License plates are mandated for liability and anti-theft purposes. Your personal phone is both private and has no other pre-textual reason for law enforcement to access it.
"The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."
Cell location data belongs to AT&T and Verizon, not the accused individual. As to such third-party data, there's a general principle rooted in Roman law that third parties can be compelled to provide documents in their possession to aid a court proceeding: https://commerciallore.com/2015/06/04/a-brief-history-of-sub... ("In an early incarnation of mandatory minimum sentencing there were only two offences that automatically attracted the death penalty, treason and failing to answer a subpoena. Subpoenas as a tool of justice were considered so important that failing to answer it was a most egregious violation of civic duty. A person accused of murder may or may not be guilty, but if a person refused to answer a subpoena then they were seen as denying Jupiter’s justice itself.").
Those principles were incorporated into what's called the third-party doctrine half a century ago: https://en.wikipedia.org/wiki/Third-party_doctrine. But by then it was already an ancient principle.
How about this part of the amendment?
> "The right of the people to be secure in their persons against unreasonable searches shall not be violated"
Isn't treating people like suspects (investigating them, searching their belongings, tracking them, etc.) merely because a third party claimed (and of course GPS is never inaccurate) that they passed within some vague proximity of a crime scene a violation of their security in their persons? Do you really have reasonable suspicion that every individual among the dozens (or more) you dragged into your search may have committed a crime if it's clear the others are there for unrelated reasons?
People (maybe not you, but most humans) feel threatened when all their moves are being tracked. There's an implicit threat of physical harm even if it hasn't occurred thus far. Not to mention there's also the risk of a bad actor (read: including law enforcement insider) stealing your tracking data that was supposedly only ever being used for good. It's a real threat to your security, and you have a right to be secure. If another person is going to threaten a free person's security, they sure as hell need both the legal authority and reasonable suspicion of a crime. That is the amendment.
Where to draw the line for "reasonable" here can vary somewhat, but I think most people would agree that if you have 3 people all in close proximity to a crime, you could justify having reasonable suspicion of each individual of being involved. If you have a hundred people walking in a half-mile radius, you clearly don't. Idk where the line exactly is, and circumstances can affect things, but somewhere between those seems like a reasonable place to start.
> "The right of the people [1] to be secure in their persons, houses, papers, and effects, [2] against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."
The clause labeled [2] limits the scope of the clause labeled [1]. It's not a free-floating right to "feel secure" against anything--people following you, etc. It's a right "to be secure in [your] person" "against" a specific intrusion: "unreasonable searches and seizures."
If it said: "you have a right not to be mauled by lions," that wouldn't mean you have a right not to be eaten by hippos. Much less that you have a right not to "feel" threatened by the prospect of being eaten by hippos.
Typically a good presupposition when the Supreme Court decides to hear the case.
Cell tower info isn't at issue here.
"But after two months of working the case, all leads had gone dry. So police applied for a geofence warrant directed at Google and all its collected and stored cellphone location information.
A state magistrate judge found probable cause to issue the warrant and authorized the disclosure of Google's location information for an area the size of about three football fields around the Midlothian bank at the time of the robbery."
Furthermore, the last major SCOTUS case regarding this issue[0] had some very interesting dissenting opinions specifically on the question of "Does the 4th Amendment only guarantee property rights". Justice Thomas made the exact same argument you made. Justice Gorsuch took your argument and twisted it inside out. He specifically argued that because the 4th Amendment is a protection on property, the third-party doctrine should be thrown out entirely, and that you should still own your personal information even if you have to lend it to a phone company in order for them to connect you.
So yes, there are valid arguments for the other side, even in the "4A only protects property" regime.

There goes my fucking morning :P
As of now, most of these jurisdictions are a FLOCK search away, with absolutely no warrant, oversight, warrant, or anything. Like, all of these abominations https://maps.deflock.org/?lat=37.5620&lng=-77.4559&zoom=11.2...
The cops say "someone committed a crime in this area, we need to find the perp". They can pretty much say this for any part of the town at any given time. A judge signs off on the warrant, because why wouldn't they? You don't get to challenge anything: no one is going to tell you "hey, your phone was in that area, come to the courthouse and make your case if you think the police shouldn't be given that info".
Im comparing due process with a judges' signature, compared to shit like FLOCK and other non-search warranted processes. And if the warrant was deemed wrongfully granted, the case itself can be dismissed or mistrial.
How much corporate data was just purchased rather than search warranted? Data brokers and parallel construction is a lot larger issue.
And about the cops giving that "someone committed a crime in this area, we need to find the perp" - pig's will always give bullshit reasons. Thats why I went to the judge's determination, rather than oinkers demanding everything and manufacturing whatever they want.
Worth noting that Google has changed its practice since 2019, supposedly, to keep location data on device, not accessible to them. However I have little doubt the cellphone carriers are also available to provide this data. https://www.theverge.com/2024/6/5/24172204/google-maps-delet...
Governments rapidly turning data into a liability. Data is the new oil is out, data is the new toxic waste is in. The consumer sentiment continues to get worse and worse as it becomes clearer and clearer that we are being intruded upon at will. It would be excellent to see some progress, in expanding & respecting our human rights to privacy.
There are many laws in place in EU which forbids many kind of practices which infringe on privacy, but the issue is that governments don't really enforce them proactively. And in some cases where they are the ones breaking them (e.g. by enacting law that is not compatible with EU Charter or ECHR) it will take long time to get judgement which forbids the practice.
Often the path is that you complain to DPA, you appeal to court, you appeal to higher court, (repeat last step X times), during court appeals you may need to wait for CJEU ruling and finally you might be able to file appeal to ECtHR.
In one "recent" case from Finland the original DPA decision was issued in 8/2020. I'm not sure how long this exact case took, but there are some recent decisions which took 5 years to issue. It was appealed to administrative court and court made request to CJEU on 11/2021. CJEU gave ruling on 6/2023. Administrative court gave ruling on 12/2023. It was appealed and higher administrative court gave ruling on 6/2025.
So it could take 10 years to annul an illegal law or practice.
well then we know everyone who went to Epstein Island from their cellphone records
Congress must subpoena them ALL
especially the one that went all the way back to Trump Tower, who was it?

In theory your comment may be a rebuttal to the 'largely academic' assertion I made, in practice it's largely a distinction without much difference. Your rebuttal is a pretty remarkable, eccentric claim in the context of the vast majority of telcos that will share the data for a profit (as I put it, 'profit from the patronage [of the police]'). Whether the request comes in the form of a warrant -- again -- largely academic in such case. Your assertion requires some strong data to overcome the evidence to the contrary, if it is intended as a rebuttal.
It's also worth noting illegally executed warrants don't stop you from getting the data. I've had cops force a hospital to search me before, then get the warrant actually signed after they did it. It didn't stop the hospital from executing the warrant, it just means they evidence couldn't be directly used against me. That's another lever they have, illegally execute a warrant, get the evidence they can't use in court, then parallel construction. Sure your lawyer can argue "the fruits of this warrant have to be tossed out" but it doesn't mean dick -- they already secretly used it to get other evidence that won't be tossed out.
The "strict guardrails" don't work. Never did.
Here is the LLM's summary of the current legal issue at hand:
Attempting to determine the identity of an unknown individual co-located with a victim at a specific time requires a reverse-location query. Because the Supreme Court has not yet established a unified national doctrine for these searches post-Carpenter, lower courts are highly fragmented. Many magistrates systematically refuse to authorize geofence warrants or tower dumps, citing the lack of individualized probable cause for the peripheral, innocent devices swept up in the geographic net.
And indeed, in my case, the police were not able to conduct this geofenced investigation (which would have instantly idenitied the person).
