> There were actual, real, violent outbursts. If you put yourself in the shoes of a police officer, you might understand the police' reluctance to stand up to a potentially armed and certainly aggressive mob without any protective gear, and in completely standard police cars.
That all sounds perfectly fine, reasonable.
But why are they kitted out like stormtroopers? South Korea has much, much better organised political protesters/rioters and their Combat Police[0] are much, much better at their job than it looks like the US equivalent are, and all they've got is standard riot police kevlar armour, clear plastic shields and the helmets. Note that they don't look like troops occupying enemy territory either[1].
I can't see any justification for local police forces having military vehicles, and I think the optics of police in camo are hideous, unless that is actually the message you want to send of course.
I realise that the USA is legitimately exceptional in the number of guns floating around, illegal and legal, and that it is far, far more violent than any other first world country, for whites and blacks but why the shoddy police militarisation? You're not Mexico, there are no gangs as organised and competent as the Mafia who go toe to toe with the police.
And if a paramilitary force is needed, why doesn't each state have 100 full-time SWAT guys (or more, I really have no idea how many New York or California need.) and 400 guys who are cross trained? If you need more than 500 men with machine guns, it's time to call the National Guard.
