At what point are Americans supposed to assume they’re real cops, or assume they’re not?
I didn't think about that. Law Enforment agencies accross the country should be in an uproar.
It will probably take some cop getting shot by mistake before anything is said or done and the media probably won't touch the story regardless, so the sheep will never know when it happens.
If they don't come in the day time, knock and wait for you to answer the door, to present you with a warrant, then you must assume they are not real cops. Sure they might be, but if they want to act like the thugs, we have no choice but to treat them the same way.
Two to the body and one to the head. Even thugs may be wearing body armor.
