My cited source is a legal decision, written by a judge.
I've followed Project Veritas and yes they go undercover for right-wing causes, but I haven't seen evidence of them being deliberately untruthful in their reporting.
The real case here is that imho we should all start to (1) withdraw from outrage, (2) expand our bubble to cover all sides.
I've done the latter, it helped with the former, although I'm not there yet.
I'm guessing you'll claim that Project Veritas was truthfully reporting what Hopkins told them, and it's not their fault that he changed his story once he talked to law enforcement. Even though he also told the investigators that his initial affadavit was written by Project Veritas.
