Police Violence: Yay or Nay

Police officers and first responders are not supposed to act violently, they need to be the hero. Unfortunately, that's not always the case. There have been many court cases and disputes regarding police brutality and even death. It is hard to make the assumption that a police officer would harm a suspect deliberately, even when the suspect did nothing wrong. With the proper training and education, police men and women have the skills to determine what actions need to be performed during altercations. I find it very difficult to find a police officer guilty of violence. I would like to believe that they made a conscious decision. One that they will have to live with forever. Innocent until proven guilty, right? With the use of a dash board camera, back up called to the scene, police chief interrogation, I would think that would be enough for a judge to make his final decision. Too many spectators talk about the case and cause a hype that would more than likely not happen if the officer and suspect were of the same race. Every human race has experienced police violence or an altercation from first responders at some point and time. It's just that some make a more fascinating case than others.
