Having been a police officer for 30 years, I have a different perspective than others commenting on this topic. Everyone is influenced by their own life experiences and social biases. As I have watched the various incidents from Ferguson to this Texas pool party unfold, a common thread ties them all together. Without exception, each incident would have had a different outcome if the subjects involved had complied with the police during the interaction. I am not siding with any specific officer's actions, as some of the police tactics were unprofessional, up to and including criminal. My point is, like it or not, we live in a country of laws, and the police are charged with enforcing those laws. Just because we may not agree with a certain law, doesn't exempt us of having to follow the law. If we don't agree with the law, we need to work to have that law changed. Challenging or refusing to comply with the police only escalates a situation. The police are legally empowered to "use whatever force is necessary to effect an arrest". Use of force is never a pretty thing, and when seen on a video can be shocking to the average citizen. I have personally experienced countless acts of disrespect and outright contempt of the law. I would ask a question of the most vocal critics...what should the police do when people refuse to follow the law and resist the efforts of police to peacefully enforce the law? Should the police just give up and leave the scene? If people refuse to comply and follow verbal commands, should that end the continuum of enforcement? Bottom line, it never is as easy or simple as people not involved in any given situation think. In the case of the McKinney incident, crowds can become dangerous quickly...even if they are teenagers at a pool party. I am not going to judge the officer's actions, but rather have you place yourself in that situation. What I saw on the video was a large group of people involved in a some type of volatile situation. When police arrive, they don't know what the situation is, they can only process what they see upon arrival. Police are human, and can feel scared in volatile scenarios. No amount of training can prevent all types of emotional responses by an officer. In the current environment of police distrust, the police are "damned if you do, and damned if you don't". I personally am glad that I am not starting my career in law enforcement...it is not a "good" career any longer. I go back to my simplistic bottom line...if people comply, the majority of situations resolve peacefully and without harm to the participants.
