I watched the video up to 4 minutes and a half, and so far no cop or anybody else got close to the homeless guy in ground to assist....4 minutes for c*** sake the guy might be dying by then if they shot is because they were in a hurry to get to the endangered person on the ground no? If that fast gun i8s all to not provide help once the dog is removed from the situation they might as well stayed in their car and wait for AC and or and ambulance. If this homeless had particularly vicious dog it would have been taken care before I believe, the guy is in the streets 24/7, other previous incident should have happenned and get the dog taken away or something like that, many many dogs can react like this if somebody comes straight at you (and the dog) with a fast pace and a certain attitude, for the bystander I havn't seen that part but could be recirecting, because you see the dog going back and forth, like a dog aroused behind a fence. To sumarize if the cops would have got right away to the guy to assist maybe I could accept it, they didn't shot for nothing, they also could have taser it...why not it would probably be less harmful, i believe...unless the calibration of taser and weight of dog (less that average human) would make for a deadly voltage.
