Why American authorities are always attacking their citizens freedom?
Technology is becoming too significant an existential threat to all governments. IMO, this is the "animal lashing out when backed into a corner" stage of their arc. All of the bills are coming due and they're having to answer for them.
Stuff like this incident (plus the whole surveillance gambit) just being a reflex out of fear, desperate to stay in power just a little bit longer. The funny part is, in the lashing out, they're exposing themselves and their true nature to an extent that the old illusions are fading fast. I implore people to never forget: your government is comprised of other citizens who are exactly like you; they're neither special nor omnipotent. They're just collecting a paycheck under a title.
If memory serves, I think this is also suggested in the book The Fourth Turning but don't hold me to that.
Law enforcement are underpaid, overworked, and they aren't even respected anymore. A lot are fine, but a lot of people are ending up there because they can't get any other job [1]. I don't think these attacks on freedom are always malicious, I think a lot of it is people in law enforcement who aren't capable of understanding the not-so-subtle difference between "law enforcement" and "law authority".
[1] - See stories from 20 years ago about people being turned away from law enforcement roles for having "too high an IQ". Or recent stories (such as one I heard on the podcast of a former FBI agent) about new recruits who can't read.
This is a bit worse than that. They're specifically targeting this guy because they don't like his politics, an act that is unconstitutional, but Trump and his administration has had contempt for the constitution since day one.
Republicans might as well rename their party the Democratic Fascists of America at this point.
i think it's just that the American population is the last bunch who gives a damn about it, and the pockets of resistance still makes the news... the same happens mostly everywhere else, just without much complaints.
e.g. in Hungary the authorities treat it as a felony to possess an equipment that can record video or sound and it's not obvious when looking at it. 2-8 years in prison for mere posession, i.e. even if it's turned off in your backpack. random nonsense that if it can also make phone calls then it doesn't qualify (the above is the law paraphrased).
