Need to rant
Ok if someone has a gun and it is pointing at you, listen to that person. It doesn't matter if the person is a cop, or a criminal. Its call survival people. You don't go charging at the person. If you are unarm talk to the person tell him about yourself, try to get him/her to lower his/her weapon, distract the potential shooter while waiting for backup, or something . Also while talking have your hands up, and if he's a bad guy while talking take mental notes ie skin color, does he have any scars, how old does he look, what is his behavior like is his hands shaking with fear or is his hands calm like he does have a problem shooting you. If you're armed have your gun out point it at him, and if the criminal has a hostage and say drop your gun well this is where the pen becomes mightier than the sword. Come on people you have a brain use it.
End of rant.
