That cop lid looks like Chicago P.D.; I would know... 1: I grew up in Gary which is 25 minutes from Chitown 2: My dad (Gary cop waaaay back in the day) knew Chicago cops 3: Even though I was working as campus police waay long ago, I often had occasion to drive into Chicago & had to carry my cred w/me. Lots of instances. Good guys back then, can't say the same now but they have bigger problems with communists running the city. I always thought CPD was trying to look like Britain but figured out early on that emulation went deeper than just uniforms - 'metropolitan policing' as a model was British but adopted quickly by major US cities.
...And back in the 60's, rioting was a lot more violent than the media or history books say. Let's just say the cops were MORE than justified in shooting looters & rioters!
