Frankly, a cop murdering a black guy for no reason in the middle of the street in the middle of the day is a way bigger fucking deal. I value human life a hell of a lot more than I value property. You're trying to derail into the actions of a few bad people to ignore the systemic injustices that sparked the riots in the first place.
Want less riots?
Fix the injustice. That's what causes riots. These people are responding with extralegal actions because legal actions do not help fix the problem. They just get you teargassed for your trouble.
As happened here, triggering the riots you're trying to focus on, to cover for the murderous fucks who killed a basically innocent man in broad daylight. And still haven't been arrested or charged with anything.
