Be aware during the entire time of contact with a firearm that it can go off. Law enforcement has found that choke holds are excellent methods because if they are applied correctly, they render the subject momentarily incapable of fighting. A rear attack would provide the time to apply this technique. I have seen officers attacked and injured by individuals who at the time were handcuffed, in jail, from wheel- chairs, and strapped to hospital beds. Communication is vital in these circumstances.
Someone needs to assume the role of leader.
Issue orders, direct others to act, establish other lines of communication. Often during a panic-filled situation, people look for someone to take charge. The first two priorities are treating any wounded and contacting the authorities. Again this is a good time to delegate by giving orders. Tell someone in the crowd to contact the police-if by telephone, tell them to stay on the line and not hang up until officers arrive.
