In fairness BLM was far more violent. Neighborhoods were burned to the ground, businesses were looted, people were injured, and several people were killed. Moreover, the BLM protests involved millions of people, so 14K arrests seems believable. Moreover, how many of the arrested were charged (getting arrested on its own isn’t that big of a deal).
Various parts of Kenosha off the top of my head. Most other arson cases were isolated businesses, police precincts, etc. There were also entire neighborhoods in which virtually every business was looted. We had at least a few such neighborhoods in Chicago, and there were many others across the country including many of the communities that BLM folks purport to care about.
