This is a flawed methodology for measuring success.

Solving a case isn't a single correct search. It's a tool, and a single case could have hundreds of searches associated with it.

As more regulation comes in, as it should, we should get much better auditing data that link each and every search to a specific case. This is evolving quickly at the moment, but ultimately it's up to the public to begin to push for requirements like these.

Currently departments do not necessarily require a case number, as many times a case number has not been created yet.

I think a more fair method to measure success is look at how effective each dollar spent on LE accounts for the whole picture. How much more effective did ALPR make each officer/detective on the force? Generally speaking, these are force multipliers and are much more effective than spending on pure body count. Many departments cannot fill seats even if they wanted to.

If I apply the Purpose of a System is What it Does (POSIWID) heuristic, then the purpose of Flock cameras can not be cost effective law enforcement.

> A 99.852% ineffective rate means city leaders will spend $2,009,521.50 on license plate reader technology that does not help any case."

That's not at all what it means. The cost of the system is almost independent of the usage rate of the system. The proper math is that they spent $5,575 per case advanced. Is that a reasonable cost?

I don’t think this is the right argument, and I say that as someone who wants legislation to prevent such data from being accessible to federal agencies.

Those cases that WERE solved using Flock data could have impacts worth far more than $2 million. For example if one kidnapped child were recovered, what is that worth to the parents? What about to society, who can feel secure about their kids and also actually experience higher safety due to better deterrence? That’s worth more than the few thousand dollars you could say was spent to support that one search of Flock data.

Ultimately, the data is also only as good (and bad) as how it is used. If local jurisdictions use it to solve crime and to actually prosecute criminals (rather than letting them go) then it can be very beneficial. A lot of people are frustrated by criminals not being brought to justice. And obviously, if their privacy is lost, that’s a downside, but it’s not the sole thing to weigh here.

Also that $2 mil is the cost of the system, and doesn’t include all those man hours spent running unproductive queries.

>These things aren't not law enforcement, they're mass surveillance with a badge.

That sounds like ChatGPT.

Maybe! We don't know, all we know is that allegedly:

> Those searches played a part in “advancing 361 cases.”

What does "played a part" mean? What does "advancing a case" mean?

They never solved any cases, only provided a warm lead once a day. If they solved many, they would be proud and say N cases solved. In this case N must be an embarrassingly small number since they don't use concrete language. It's like offering 5500$ to anyone that offers any information on any crime.
