>practices of bringing the machinery of the state down on the head of the average citizen for minor infractions (whether or not they are really infractions) with consequences (arrests, professional and social consequences, disappearance, torture, gulags) out of all proportion to the crime (whether or not an actual crime rooted in principles of natural justice is involved).

That happens here, it's just not coordinated before the fact. If you piss a policeman off by taking too long to pull over, they will beat you and get away with it. There are many examples of this on YouTube, here is a relatively minor one. This poor woman will be forever traumatized by this event. Those police won't get fired and it's pretty obvious they have some serious anger issues.

I feel policing and the overall justice system is the single largest threat to our country right now and if it isn't rectified will lead to massive civil unrest. This channel covers a lot of it.
