First, doing something minor like selling a prohibited item(cigarettes) shouldn't lead to death, and it shouldn't come down to resisting arrest. No one should get arrested for that shit in the first place. The guy is selling a f**k cigarette for shits sake. This is a problem with the system, IMO. To think that someone would resort to any sort of force for a cigarette is unfathomable. Second, anyone praising this asshole who shot the two officers sitting in a car are deserving of a beating of their own.
The Michael Brown situation is not comparable, IMO, because I don't believe anyone on either side really knows what happened there.
