I didn't watch the whole video, but from what I heard, the police tried to get to the shooting victims but were driven off by the protesters pelting them with objects. Someone supposedly got the victims to the hospital on their own, but only one survived.
These protesters disgust me. They've destroyed businesses (including those owned by minorities), injured nearly 1000 cops, spray painted graffiti all over national monuments, vandalized, torn down statues (including at least one abolitionist), and are well on the way to destroying the police department (which I guess will make them happy). All the while the people running the cities either turn a blind eye or cheer it on. The guy who shot Rayshard Brooks is essentially a political prisoner. What's going on is sickening.
