Okay, this video attempts to establish a time for George Zimmerman leaving on his trip to the store.
It places his start at 7:06:43 approx. But, as we know, it's not without big artifacts in it's suppositions.
It assumes a front gate that is closed and locked at 7pm sharp. Again it puts Trayvon entering through a cut through, both of which are not in evidence. Besides, Trayvon has his cell phone with which he can easily defeat the gate closing by simply placing a few calls. Then too, someone has to close the gate, right? So, who would that someone be? Why wouldn't Zimmerman mention the gate closing as reason no one should be walking around the area? And lastly, the police on their arrival make no mention of being delayed by having to get the gate opened etc., they appear to come straight in unhampered.
Anyway here's the video:
