BTW: If Zimmerman had taken the police dept up on their offer of a car w lights and a uniform then he would be facing federal charges....he was wise to remain strictly a civilian watch captain.
OTOH TM would be less likely to try to murder a uniformed security guard. He'd know that his opponent is certainly armed. Thugs do not kill for an idea - they are opportunists; they would wait for someone smaller, fatter, and in civilian clothes - like GZ, for example, in a dark corner away from witnesses... an ideal victim, unless armed.
yeah he wanted to be a cop so bad he turned that sweet deal down.
