There is a common thread of over-zealousness and an unbecoming enthusiasm for using force in most of these cases. This has the undercurrent of authoritarianism and is not compatible with civilized society. The whole idea of law enforcement is they have the training to deal with confrontational situations with some degree of control and maturity. They have the training, weapons, access to backup and near endless resources. Any confrontation with an individual is already heavily biased towards their side, to lose control is more than reckless. For situations beyond basic law enforcement involving more than one person, for instance a riot or a gang, usually there are more specialized teams and strategies.
