I'm confused-do you support peaceful protest, or do you think that protests always descend into anarchy and require assault rifles to be brought out to kill some people?

What if police attack a peaceful protest--say trampling a lone person with horses (https://www.newsweek.com/la-protestor-stomped-police-horseba...) or shooting a reporter standing by herself (https://www.cbsnews.com/news/reporter-los-angeles-protests-r...)? Is there an assault-rifle shaped solution to this kind of anarchy?
