As for the first one , he got out of his car which is rule number 1 on what to not do when getting pulled over . Then , he swiftly turned around into his car to go grap something , police officers are trained to recognize this as a withdrawal . This guy was simply not educated on what to do during a traffic stop and got shot killed ? because of it , which I agree is sad . As for the second one , cops were told he had a gun . When the car pulled up in a poor , unsafe manner the kid went to reach in his pants , police thought this was a withdrawal of the weapon he had . and died because of it . For the two examples you provided , it seemed to be a lack of education issue . In both cases the police rightfully feared for their lives enough to use lethal force . I don ' t know if those police officers were convicted or not , but by the looks of it they likely were not . Dylan Roof complied with police in a correct manner and lived . In the examples you linked , they did not and unfortunately paid the ultimate price . I ' m sure you can look up the court rulings on the cases you are suspicious of where the police were not prosecuted , and then be convinced otherwise by reading the Judge ' s statements . You mean like the one who was suffocated after repeatedly stating that he can ' t breathe ? As for this one I am unaware of and can not make a comment of as I have yet to see the situation .
