zimmerman to trayvon martin, and the only person who has testified in this entire case as to whether or not that gun stayed holstered the entire time has been the man who is charged with the murder -- >> right -- >> -- of trayvon martin. >> john kelly, what do you think of that? >> going to what zimmerman's options are. one, he could have stayed in the car, left the gun in the car, throw, followed 30 feet behind him, and we also don't know how the confrontation started. a lot of people assume that trayvon threw a bunch that broke zimmerman's nose. that could have been a head-butt when they collided. could have been a knee when someone was tackling or when they went to the ground together. there's no doubt that this gun had to have been drawn, brought up, put in his chest, fired cleanly one shot during that struggle if he was yelling for help.
