Yes, but how do you know that? And why should we believe it?

We're literally in a thread about wrongful conviction. Evidence. It matters.

Thats certainly in the realm of possibility but the evidence of that needs to be clear. Accusations like that are one step removed from complete paranoia.

Well the evidence would have to be clear to deport a single person. But a general trend could be enough justification to shut down immigration from certain countries. That is not a personal punishment like a deportation, so it does not need conclusive proof (which of course doesn’t exist, there is no country which sends exclusively or predominantly bad immigrants to the US).

The only difference between an "assassin" and the actual Mr. Rogers is the word of the gestapo-lite thugs in ICE.
