The cops escalated every situation they arrived at.
The cops and ICE escalated an otherwise peaceful situation.
Agitators unrelated to protests have been known to kick shit up, such as during black lives matter protests when white supremacists would break windows. https://abcnews.go.com/US/man-helped-ignite-george-floyd-rio...
Anyway, if the cops weren't there, there'd be no fires. Ergo the cops shouldn't be there. Seems like a pretty simple algebra to me.
The "just submit" ideology that people seem to be touting demonstrates a lack of understanding of American psychology. The country was founded on revolution against a despot, that's the core American value. You can't deal with a population like that by sending in storm troopers, that will obviously just escalate the situation.
The government needs to be realistic about the situation and seek alternative measures if their goal is to deport the neighbors of people who love the 2nd amendment. Perhaps they could simply give up on that goal, that's what I would advise.
I think you're misunderstanding the audience. The Trump administration is not trying to convince or even deter these protesters, all of this is theater for middle America at home watching this on TV. It's a battle for their votes based on who wins the propaganda war by looking less reasonable on the news.
