The proper actions look obvious to me....beat down the perp, put a towel around the kid and get him the hell out of there and call the cops!
WHY is it so OBVIOUS to us? I still hear people discussing this as if there was another option.
It's OBVIOUS to us because we would not have stopped to first consider what it would cost to act thusly -- and sometimes doing the right thing definitely incurs a cost in terms of unexpected personal and occupational blowback. Been there, done that, got the kick in the ass for my trouble and I'd still DO IT AGAIN.
Apparently, Sandusky's proclivities were an open secret around Penn, and for years; exposing the university to scandal by blowing the whistle on the guy, and his protectors, had to be a consideration in the decision not to call the cops. McQueary chose to self-protect and he's paying a price anyway.
Don't misunderstand me; I'm not making excuses or offering "options", just describing the depths to which society has sunk in these matters.
