I've watched hundreds of police apprehension and bodycam videos. This particular video is quite common. Here are some conclusions:
1. Women should not be out on the beat or in the cruiser. Most are useless in these types of situations, as was the female officer in this situation. Many make the situation worse, where their male partners not only have to worry about the suspect, but also the safety of their female partners.
2. The dehumanization of cops campaign that ramped up even higher the last couple years has only encouraged more of the behavior of bystanders that you see in that video. Time and again in black neighborhoods, bystanders either refuse to help officers, encourage perps to attack them, or join in on the assaults. People were shocked by that video of the four year-old last week when he was swearing at and kicking the cop. They shouldn't be. The kid has been socialized to think and behave like this.
3. You can see the reluctance of the other officers to use weapon/force that was needed in that situation to prevent the cop from possibly suffering serious injury. People are maimed every week after having their heads bounced off of the floor after a punch or after being dropped on their heads. If not a gun, then certainly a baton or taser. We all know who is to blame for this unwarranted reluctance. Those folks need to own their votes, of course.
