As it turns out, if there are no consequences, then you can actually do this.

"After the January sweep, the man who led it, Chief Patrol Agent Gregory Bovino, said his agents specifically targeted people with criminal and immigration histories. However, a CalMatters investigation revealed that the Border Patrol had no criminal or immigration history on 77 of the 78 people it arrested."

so just being an immigrant?

the question isn’t “who’s going to let me”. The question is “who’s going to stop me”

tRUMP: "Lol...oh, you're serious? I. CAN. DO. WHAT. I. WANT. AND. NO ONE. WILL. STOP. ME.
ARREST THAT JUDGE, they are, err, umm, secret members of ms13 or something!! Beautiful arrest. Tremendous. People are saying it was the best arrest ever!!"

oh you can’t? and what is anyone gonna do about it?

Racially-profiled stop and frisk arrests are official policy in multiple US states, and have even stood up to court challenges. Stooge judges have been around even long before Trump. Maybe the judge forgot he lives in America.

Next week: “You just can’t walk up to people with judges robes and intern us”

The Nazis think they can.

I've seen police in german trains doing precisely this.
