"While the summer of 2020 experienced 100 days of violence and destruction in cities, according to the the U.S Department of Homeland Security, the most recent CCC study of 7,305 separate events in May and June suggests that 96.3% of events involved no property damage or police injuries"

So 270 violent protests in that 2 month span then? Not trivial.

There's a distinction between "violent protest" and "protest at which at least one (potentially minor) incident of violence and/or vandalism occurred" - the latter seems to be what those statistics are counting.

If 10,000 people march through a city and one of the 10,000 sprays graffiti on a single store or breaks one window, most would not call that on the whole a "violent protest." How many were in that category and how many had truly widespread violence or more severe destruction? I'd love to see a source capturing that. Anecdotally though, in online discussion I often see people treating it as a given that BLM protests laid waste to whole neighborhoods in multiple cities, which seems more like flat-out misinformation...
