I am a big proponent of call 911 , and leave the line open . then and only then escilate thro verbal confrontation to physical if needed . If the police can arrive well great its thier job to handle the situation . If not no one will be raped/abused because some folks feel safe on officer response time . I should note tho that this is not a smart attitude , and my youngest child is in college . This does free up my actions some . I have to say that if your not an officer and sworn to effect an arrest you should call 911 and be a great witness .. I am in a strange place where by the family of the wonderfull young man i just shot may , and i say may get a pickup on judgement . Sadly if you are not confident of what you may loose in civil court then you cannot afford to help an officer further than making a call . I dont like that either but its the facts of life today .
