"The police chief of Quakertown, Pa., led a group of plainclothes officers to disrupt a peaceful high school protest."

19. If they're plainclothes, then for all intents and purposes

they were simply big, burly (mostly) white men attacking girls. No other way to see it at first glance, IMO. Police these days are above the law, know it, and make the most of it. I'm former law enforcement... and former military police. The units I served with in those days could never have gotten away with this kind of crap. I knew more than a few who were totally unhappy they let females into the military police, and some in civilian positions who felt the same way... but no one would take down a child and choke her for simply holding a sign and protesting. At least back in those days, the Constitution still meant something in this country.
