I agree with the points being made. They show that the situation is avoidable if the police would have seen that the man was making no attempt to struggle. As said above there was no reason for shooting the man.
The big point that agree with is the police being trained to shoot then think mentality. This point makes me feel sad as a human, as the point is mostly teue its sad that a person would kill another human being for almost no reason. The reason that I think this happens is because a person can be a police officer right put of high school allowing for less trained officers.
