The ones who enjoy the cruelty don’t feel like real agents—more like Proud Boys in disguise (pure speculation, of course). And saying “they’re clearly ICE, look at the gear”? Please. You can buy an ICE jacket on Amazon for £16.99. I could be ICE in London.
Half the Proud Boys, etc. were already in law enforcement. Law enforcement in the US is incredibly fascist and they act with literal immunity in most cases. Nothing like in Europe. In fact, that was one of the first things I noticed when I first arrived in Europe decades ago.
