3 Black militia members injured in negligent gun discharge, may result in charges

What set off the dynamite was the city being weak and laying down, which made the protestors think they can get away with all the crime they've been committing. A large percentage of these protestors are criminals taking a short break from their normal occupations of murdering each other, robbing and selling drugs. They're not going to suddenly convert to being good people because they're yelling protest slogans. They're still violent and highly impulsive criminals.

What do they understand? That their actions will lead to being put in a dirty stinky cell for weeks, months of years. That's all.
