They are losing control of the narrative and in some cases, the public spaces - no matter how they spin things, there's cell phones everywhere recording them, people are chasing them away with numbers, whistles, and phones/cameras, people are actively trying to dox all of them. Their boy Ross and his family had to be moved to a safe house after he murdered a woman. All of that leads into them having to try and intimidate people even more and to try to reestablish control over the population by doing these raids and pointing their sidearms at people and picking people out to harass. They can't identify these agents for the most part (although there is a large number of people who are quietly working to doxx every one of the ICE agents) so the agents don't have to worry about being reprimanded.
