The only official webpage of the park I could see (Charles River Conservancy) states that the park currently closes at 9 p.m. The same for Google, though I am not sure where Google gets that information.
If a crime didn't occur, could someone still be charged with resisting arrest?
yeah, happens all the time.
our system is screwy. if you haven't broken a law there's vague charges like 'disturbing the peace' or 'disorderly person' which basically means you pissed off a cop.
i've gotten a ton of those when i was a kid and talked my way into jail.
also, you can get resisting arrest by itself even if you shouldn't have been arrest in the first place. it's some catch 22 shit.
basically, cops are trash as the poor but they've been entrusted w/ brutalizing the poor to keep them in line. along the way, some of them may do a kindness or whatever, they're just lower educated people like a lot of us but they make a good living which is dying out for average joes in america.
i wouldn't say the upper class respects them but they afford them impunity so long as they punch down or lateral. cops have done some evil shit over the decades but really, cops are just people. i didn't get that when i was younger but the same folks that join gangs, military, etc. can't hate em all [but maybe feel safer when they're not around].
