Just about everything about this comment is factually incorrect. There were two incidents. In the first, a group of people (allegedly) were setting off fireworks and spray-painting vehicles, fled from responding local police, and one of the group shot at them and injured an officer. In the second incident, a disturbed individual fired and killed a detainee, injuring two others. Then he killed himself.
So, no anarchists, no ICE personnel shot, and it was easy to find the news stories about both incidents. ICE has shot several people, and begun using more violent tactics, so it would at appear that they are escalating.
