I know that there are some people out there who shouldn't be cops and give them bad names and that the mechanisms that protect those bad cops should be torn down. But this isn't the be all end all. There is another side to the medal that is clearly shown in this video.
This cop was doing his job right. Yet these clueless bystanders lived such a sheltered life that they didn't even realize that lives were being at stake here. Even their own, had the gun went off when the cop and suspect were fighting over it. They were just standing in the zone of danger, filming and criticizing a cop who was desperately trying to not die.
