Back to the speculation, Martin didn't have a car,and in the call (long version) the kid bolted and then Zimmerman lost him and seemed to be returning to his vehicle. I myself kept a safe distance when calling in that fellow I posted about earlier. We don't know yet how close he was following, its not evident with the available info.
Hey... One night I was awoken by two men in their early thirties beating on each other beneath my bedroom window at 3am!.... The one was my neighbor to my surprise. I yelled out loud enough to wake the neighborhood.....”Knock it off or the police will be here shortly and they’ll make you knock it off”.....they stopped immediately. Broke it up... and the neighbor hollowered out an apology on his way thru the hallway. I did not respond.
