Don't forget you're trying to compare almost 2500 protests involving 10's of millions of people over several months nationwide.
90% - if not higher - is a resounding tribute to civil restraint given the righteousness of their cause and the justifiable anger that fuelled it.
Actually the number is 93% BLM protests considered peaceful. And even in the small number where violence occurred, not every participant that was in a protest that was violent participated in the violence themselves. So the number of people that would be considered problematic is extremely small.
And don't forget what I mentioned before...
At least some of the cases where violence and/or looting occurred, those involved were not part of the BLM protests, but were merely using the protests as cover for their crimes. In other cases, it was right-wing agitators who were causing the problems.
Compare that to the Truckers rally, where pretty much 100% of the protests have caused problems, and here in Ottawa it appears that pretty much 100% of the troublemakers have actually been associated with the rally.
