It's not anti-democratic, it's just pragmatic.

Yes the US is a democracy, but a lot of our systems suck ass and are also close in proximity. You DO NOT want to get into legal trouble in the US. Our justice system is beyond fucked. If there's one way to permanently ruin your life in the US, it's getting into legal trouble. You're better off smoking crack cocaine, that's probably healthier for your livelihood.

I don't know about China's legal system, but even assuming it's more fucked, it's all the way over there. Not here.

The main trouble with Flock and companies like them is that they attach to our broken systems like a tumor. If the system fails, which it often does, these accelerate it and make it worse. If you get falsely accused of something or piss off the wrong PD, this shit can ruin your life. Permanently and expeditiously.

Even if you are the most Moral Orel you should be skeptical of these crime reduction claims. They don't just beat down crime, they beat down regular people, too. And if you ask them, they don't know the difference.
