Who needs a spycam when Zimmerman gave us an account of everything I said?
Zimmerman: Hey we've had some break-ins in my neighborhood, and there's a real suspicious guy, uh, [near] Retreat View Circle, um, the best address I can give you is 111 Retreat View Circle. This guy looks like he's up to no good, or he's on drugs or something. It's raining and he's just walking around, looking about Zimmerman: Yeah, now he's coming towards me. Dispatcher: OK. Zimmerman: He's got his hand in his waistband.Zimmerman: Somethings wrong with him. Yup, he's coming to check me out, he's got something in his hands, I don't know what his deal is. <-- Zimmerman finds Trayvon to be a threat.
Zimmerman: **** he's running. Dispatcher: Are you following him? Zimmerman: Yeah Zimmerman: If they come in through the gate, tell them to go straight past the club house, and uh, straight past the club house and make a left, and then they go past the mailboxes, that's my truck.. <-- Zimmerman exits his vehicle and follows Trayvon.
After that we do not know what happened until the two were seen fighting and Zimmerman killed Trayvon. If Zimmerman never exits his vehicle to follow someone he clearly found to be a threat then this never happens.
