http://www.dailymail.co.uk/news/art...ot-hero-disarmed-possible-church-shooter.html A perfect example of why you should immediately comply with an officer's instructions. Last summer an off duty St Louis officer when he decided to intervene in an incident was shot by responding officers. No amount of training is going to give the officers ESP so they can tell who the good guy is when they arrive on the scene. I really don't know why so many people have such a hard time understanding this. If you are involved in an armed confrontation it's best not to be visibly armed when the officers arrive and if you are, expect to be ordered to disarm and perhaps even cuffed until things are sorted out. Responding officers most often don't know what they are dealing with until they arrive and see for themselves.
