You are naive to think police can’t turn a peaceful protest into a TV photo op for Fox News.
And, it’s also naive to think that all the protesters are on the same side. Instigators are from either no side and the other side.
During the George Floyd protests I was walking home and witnessed agitators turn a peaceful protest violent within minutes. There were at most 10 of them out of a crowd of 500. When I got home, the news described the protest as being a violent one.
You and a lot of people here need to look more critically at what you are seeing online and in the news.
