The darkness that this happened in was something that I honed in on from the beginning. I was surprised, through researching it, to find out just how dark that part of the neighborhood was around 7pm. There were no outside lights on in that area, no street lamps, no porch lights, etc. It was really dark. Your eyes would be straining just to see a couple of feet in front of you. Z was using his flashlight to be able to see. M didn't have one. M could very easily have 'followed' Z without being seen or noticed until he was up in Z's face; the element of surprise. That alone could put fear in someone.
I recall when this case first broke, I made some comment about it being dark and got attacked by a pack of wolves claiming that it wasn't all that late, and it was still light. Well, I guess those pics that the brother took, put that to rest. It was VERY dark. There was also a picture of an object that looked like a switchblade knife to me. But if that was discussed in testimony, I was taking a break. Li'l Trayvon may have been armed after all. Not sure what happened to it or if the object was ever analyzed for prints, or if it was just overlooked in the dark.
