that was AFTER somebody INNOCENT was SHOT! After the KKK did that for so many years and now that most police usually endorse the KKK grand wizard trump, people are gonna be angry. I dont agree with violence. But when violence happens against one guy for no reason, he or his friends and family will avenge him. There's evidence that instead of taking black people to jail or not bothering them cause they didn't do anything, police would take them around the town in their car as they are handcuffed and bump them till they get super bruised and bleed and even end up dying. A lot of black people have died in similar situations and it was covered up as suicides.
