"Heckling" ICE is protected first amendment speech. It is absolutely unacceptable for them to take any negative action whatsoever against someone for that. Law enforcement officers need to have some fucking professionalism and not be thin-skinned babies. Anyone who can't handle that needs to be fired immediately.

Distinguishing who is legally allowed to be in the country from who isn't is literally ICE's entire job. If they aren't capable of recognizing official government documentation that definitively proves someone is allowed to be in the country, get them some fucking training before they go around arresting people.

The people who are entrusted with the enormous power of enacting violence on behalf of the state must be held to a higher standard than the people who are entrusted with protecting nightclubs from 20 year olds trying to get booze.
