I really feel like things like this should be based on case by case circumstances. No two situations are the same and no two situations should be treated the same. You can not paint any given situation with the same brush as another and the law needs to reflect that. To may factors come into play with things and you should go into situations with an open mind.
How do you say a law officer is above the law? If a person commits a crime, he or she should face the same penalty whether their a cop or a criminal. For the most part, there is some built in leeway with sentencing, and mitigating factors can and should be applied when appropriate.
Yes, I feel that in many cases, police officers are taking the lives of innocent civilians instead of protecting them. This must change. In the instances where a police officer has shot someone who was unarmed, the case should be tried as manslaughter or murder. Police officers should then expect the same punishment as anyone else.
Shooting an unarmed person should have the same consequences as if they were a civilian. Many of these cases involves cops who were being overzealous and were definately not simply doing their duty. While the sentance was not really harsh enough it is a step forward in the right direction.
