I always wondered if family members of ICE members know that they are members... If I had a cousin that was ICE, I would go absolutely no contact with him, and would let everyone know that the guy is ICE. Wear your shitty mask, but people will know.
Someone should start an ICE database, where pictures of ICE people are posted, even masked. And let people who know them come forward and say "hey. I know the guy in picture X, it is John blabla". Then, bully those pieces of shit out of existence.
