Only the Jury knows.
I watched most of the trial (HLN). Those videos were messy, really hard to determine who was doing what. Jurors were able to view the videos as many times as they needed/wanted to during their deliberations.
The instructions to the jury, some 35 pages, even the crabby judge admited he was confused, and he wrote them! One juror requested to take a copy of the instructions home last night and was allowed to do so, apparently an unusual request, unusual ruling. Was this juror a lone holdout (one way or the other) and needed some time to study the instructions before casting her vote?
Look at it this way...they all (the kid, his attackers) had guns. Somebody was going to be shot, probably die. No sympathy from here. They were all guilty. The kid was just damned lucky it turned out in his favor. JMHO.
