That's just USA data though. Again, we are defaulting to the USA standards being the ones we should judge an universal problem like 'Should people riot to protest or not', while ignoring the fact that this discussion stems from a book claiming LOOTING specifically, not peaceful protests, as a valid means of expression, and a store simply exerting the right to post a sign saying they don't want to be stolen everything they have like, you know, any sane person would. It's not like the sign was magically shooting anyone with its evil oppression powers.
So you are, not only applying USA stats to a global issue when other countries (then again, most of the time only USA matters at all) are far more likely to have mass protests erupt into widespread violence, but you are missing the point and applying terms of pacific protests to a discussion that was about violent reactions in the first place.
