From my understanding, Zimmerman was following Martin. I assume Martin was aware of this and was trying to get away from him. Zimmerman called 911, they said stop following him. He either returned to his car, or was already there. 4 minutes elapse. Trayvon makes it to his father's house (while on the phone with Shonequa), then hangs up and decides 'Fuck this' and turns round and starts heading back to Zimmerman. Has this been disputed? If Zimmerman stopped following him by either returning to his car or staying where he was, and Martin turned around and went back to ask him "Hey you got a problem? Well you do now" then what the fuck?
