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...
