This is such a mischaracterization of the way ICE is operating, it's difficult to even know where to begin. And that's the problem here.
On the one hand, you have protestors just saying, "Hey, if you want to remove immigrants who aren't here legally, at least do so humanely and don't turn our streets into a literal war zone — helicopters, grenades, and all". And then in response, you have people trying to claim, completely incorrectly, that there are widespread violent protests against ICE officers just trying to do their job. And for that matter, that anyone who thinks ICE behavior is a problem just wants to allow unfettered open borders with no immigration enforcement.
You know what, when people come into your neighborhood acting like masked thugs, pulling people off the street without even bothering to properly identify them, you're going to get a few violent responses from citizens. The only place you aren't going to get that response is in an authoritarian society where protections from law enforcement are nonexistent and the citizenry is already traumatized into submission.
The proper response to what ICE is going and the frankly extremely limited violence we've seen in response is to figure out how to reign ICE in so they can maybe do their job without intentionally traumatizing people — citizens included — and, for that matter, exploiting every legal loophole to go after even immigrants who are trying to follow legal processes. There is never a circumstance under which the correct response to clear government abuse is to remove constitutional protections.
