The response to incidents involving peace officers always garners extreme responses. The actions of a peace officer that result in use of force will always be viewed as wrong or right in the public eye. People in the media that criticize police for their use of force actions are simply backseat drivers and are mostly ignorant.
Demanding a suspect to show his/her hands instantly starts the process of determining whether use of force is necessary. Keeping hands out of sight makes the officer question whether the suspect is concealing any life threatning weapons. The media, government officials, and college professors often do not know the true essence of this question. A peace officer risks his/her life when it comes to use of force, but at the end of the day the officer will choose their life over the suspect's. They have a family to return to, and if this suspect jeopardizes this by threatning their own life, then the officer will use their training to do what is necessary to subdue the suspect.
It cannot be overlooked that media members, government officials, college professors, and community members feel more threatened by their peace officers because there is often a sensationalism of an incident that involves use of force. Any action a peace officer takes is either celebrated or condemned. One day there may be a story about a group of peace officers risking their life for the life of another, then the next day the same department could be criticized for taking the necessary action to subdue a suspect.
As far as the profession goes, there are people that believe if you don't hold a 4 year degree, then you cannot hold a gun. The training a prospective officer must endure is equivalent to that necessary for any profession. Prior to being hired, officers often endure mental as well as their physical training. They must pass BCI/FBI background tests. They must pass exams pertaining to their department. They must serve as officer in training with a tenured officer, who will help determine the officer's readiness. This will also help the officer determine if he/she is mentally/physically prepared for the profession their self.
As there is in any profession, there are employees that become too 'lax about their job and take actions not endorsed by their department, training and profession. Unfortunately, these officers live in the public eye and any action deemed unnecessary diminish the view of the profession. Other professions are not so lucky. An IT engineer, an accountant, a doctorate degree holder, could be fired, but the public will never know about it. In the same aspect, there are officers who condemn certain actions by fellow peace officers, as well as approve.
In today's society, it is more of a crime to support peace officers than to commit an actual crime. So, I dare you, to say something about peace officers in public and see what kind of reaction you get.
