I also do not understand why so many people would cover for EA, to the point of being looked at themselves, if that is the case (that several know what happened.) I know I would not have, unless I was a part of it, even with a friend, in something this serious. And Imo, if EA is the perp, he attempted a sexual attack ,which is not a group activity as a rule, and maybe had "help" only later. But not "in" on a plan. IMO
Also, yes cameras are everywhere but look at how seldom they actually help in these cases. It is noteworthy when they do ,i.e Hannah Graham, Imo. I don't think most people are that aware or alert to cameras for the most part, especially if intoxicated. We have seen clips from other cases ,like Lauren's, but none that helped.
