There are mobs because there is so much inhumanity in the way Ice is handling their business.
There are mobs because they know if they get in the way enough, blow enough whistles in peoples' faces, film and threaten enough, and just generally berate the officers sufficiently, something bad will eventually happen and they can get it on camera. This is baiting. That's the gist of it.
And who do you think we hire as Ice agents? Not trying to be derogatory, but if you're in the FBI, secret service, special forces, Texas Rangers, etc., you're not applying for a job as an Ice agent. So, we've got regular, low-level LEOs having crowds of agitated and agitating protestors launched at them. What's eventually going to happen? At this point, it's just the law of numbers, even if most Ice agents are trying really hard to be good 99% of the time.
