America is an authoritarian country for decades now.
It first dawned on me when i visited NYC some 30 years ago. I stepped over some arbitrary yellow line I wasn't supposed to - the uniformed cop that noticed that went from 0 to 100 in 0.1 second and behaved as if I just pulled a gun. Zero time to reflect and assume I might have made a legitimate mistake. Since then I've visited U.S. >150 times, and in my experience it was always thus in the U.S. - the law enforcement is on hair trigger and the populace has seemingly grown used to it and considers this behaviour normal. Geez.
(Go live in any northern european country for comparison. Any interaction with law enforcement is almost certainly going to be pleasant, cordial, and uniformed police typically does not rely on threats of violance for authority).
America is not NYC. NYC is proud of its police-state apparatus. Most of the rest of the country is very different.
NYC police seem insane lmao. For some reason various precinct accounts have made it into my social media feed, and the last time I saw the they were bragging about stealing some old ladies less lethal defense weapon.
