If you think about it, logic still fails, but WWE doesn't really have to go in to detail when dealing with a young audience. Somebody mentioned this, but why not narrow it down also by the size, height, and physique etc? I mean, If it was Beth then surely you could tell unless the attacker was wearing layers or something to hide it.
Yep, you're right... there's so much superficiality in this whole thing...
(Or is maybe on purpose...? .. Nah.. what am I thinking..)
