Flaccid doughy physique.

They have plenty of restraint but only when the protest or march involves the far right. They get let off with pretty much anything and cops applauding them and chatting with them.

Anyone else though gets the tear gas, rubber bullets and beating (especially journalists).

It is pretty clear that the police in the USA are far right fascists.

Your recollection of what?

The best advice for anyone being asked basically anything by a cop is to tell them you aren't answeing them. You have to actively use your 5th amendment right and state you are using it. If you just say nothing at all then they can use that against you. They can't if you "plead the 5th" or tell them you aren't answering.

Loads of people incriminate themselves when they shouldn't. Any lawyer will tell you to say what I said in response to police questions.

If a "good cop" works along side a "bad cop" and does nothing about them then they are not a "good cop" they are a "bad cop".

Not a fringe benefit but the reason many become cops to begin with.

The only thing you should say to cops is "I'm not answering that question"
