LEO=Law enforcement Officer. so I guess the name is not the real description. Protect and serve is more a motto. enforce the law is more the description.
Actually, it is technically a misnomer. There is no branch of government that has a constitutional duty to ENFORCE law. The courts, by nature of their expressed duty of INTERPRETING law, subsequently applies the law as a result. Police officers, being officers of the legal process, are in turn designed to bring those suspected of crimes to trial where the courts can determine their guilt or innocence. This is key. Innocent until proven guilty is a corner stone of the American justice system. It is why "allegedly" is so common a term. Killing a suspect is in no way a function of the police force. It is in fact a complete failure of their primary duty which is to bring the suspect to the judicial process. It is only through complete laziness and corruption by those in positions of authority applying their on biases, prejudices, and beliefs without respect to the spirit of the law that any other outcome is possible.
Every shooting death committed by a cop should be evaluated as if a citizen has committed the act. THEN it must be considered that through their training, duty, and access to less than lethal means they are capable of diffusing a situation in a manner that a normal citizen cannot. It is a burden but not an unreasonable one given their position.
Plus the two pussies were wearing bullet and stab proof vests. Soooo yeah.
