Absolutely ridiculous law. I pray to God the US does not follow. That being said there is some strange law trickery where passwords and pins are safe but biomentrics aren't. We should just standardize it in the US.
The US has been doing that for years already. There's plenty of stories of people (US citizens included) being detained by border agents in US airports for refusal to provide said agents with access to their devices.
Maybe there will be some reasonable limitations on this. Say only allowing it with in 2500km of the borders. Everything inside that is fair game for immigration officals.
But what do you think about Hongkong? Do the authorities there have valid reasons to do this? Any advices for Hongkong people? for visitors to Hongkong?
