to counter 2) ICE is not police. There is nothing differentiating them from armed thugs. No bages, no ID's, no faces etc. There is no reason to do ANYTHING these people ask.

to counter 3) I would say there's a clear chick and egg here. ICE started behaving in a way that is now being met with an equal and opposite reactionary force. If ICE can stop acting like some SS wannabe force, the vigilantism goes away as well. The rules and laws are for everyone, not just some.
