It's even more that they're unmarked. They also refuse to speak at all or identify what agency they work for or even that they are law enforcement officers. They are also fastidious about proper pandemic face covering
It's almost identical to Putin's little green men in Crimea in 2014.
I'm very curious how it would play out in court if someone seriously tried to resist arrest with one of these guys. Are you really legally required to comply with someone shoving you around who won't even identify themselves as being a law enforcement officer as they shove you into their rented minivan just because they have a tiny patch that says "Police"? What about if they're not even the police, they're a federal prison guard or something?
