Tips to vet whether a person you are dating or know might be working for ICE?

I think it would be good for the community and people in the US to have ways to make sure they’re not creating relationships with ICE agents. If the community doesn’t want it all good. and obviously not meant to profile people.

1. Obviously we know some names of agents who have murdered people: Jonathan Ross, Brian Palacios, Jesus Ochoa, Raymundo Gutierrez
2. I presume they’d be pretty conservative and machismo. Maybe have some blue lives stickers on their truck.
3. Maybe tattoos, specifically Punisher. Could be police also.

What else could you use to sniff out if somebody is ICE if they’re hiding it from you?
