George Floyd died of a drug overdose did not die from the knee to the neck
I haven't seen that yet, but if that's true that doesn't change that he was telling the officers he was having trouble breathing, etc. and three of them ignored that while at least one was kneeling in his neck until he died. Doesn't change that he died at the hands of these officers in my opinion.
People have a right to be pissed about how they handled this arrest and demand just punishment on these officers. They don't have a right to burn places to the ground, throw bricks and rocks at law enforcement officers, and steal everything behind every glass they shatter however.
