I have already addressed this issue. A mind this depraved and savage could VERY likely use the little boy as a shield. Only a concealed expert marksman-sharpshooter can settle such an event.
Rushing would have to be CONCEALED until the very last-second. Not likely if McQuerey was spotted.
Next, using the boy as a shield, he threatens to crush the boy or such (”Dog Day Afternoon”) he orders the pursuer down to the floor or much much worse. A very dim scenario.
I repeat: only a concealed expert marksman-sharpshooter can settle such an event.
If McQuerey had NOT been spotted, he THEN could have cell-phoned (perhaps even photo-sent..still needs to be concealed to protect the boy,) and then positioned sharp-shooters brought in.
The guy was a dirty old pervert, naked in the shower, in the middle of a sex act. Your speculations that he could be hiding a weapon are ridiculous. Where, in his bum?
As for using the boy as a shield, etc, it’s just inane speculation that doesn’t fit at all with what we know about Sandusky and how he responded to similar situations. The man was caught in the act of molestation three times. In two of those instances, he knew he was spotted, but the witness didn’t confront him, but in the third he was confronted, but he managed to talk his way out of it. He had also been able, apparently, to successfully talk his way out a prior police investigation. Therefore, his behavior demonstrates that if McQueary had confronted him, he probably would have tried to talk his way out of it again, instead of using the terrorist/bank robber tactics you are speculating about.
Sure, McQueary was in no position to know that about Sandusky, so maybe he would think Sandusky would hurt the child if confronted. However, Sandusky was already hurting the child, and by walking away, McQueary pretty much guaranteed that nothing would stop Sandusky from doing further harm to the child that night. So, he chose to allow that harm to continue instead of making even the slightest effort to stop it.
If that qualifies as a smart decision, it can only be viewed as a smart decision regarding McQueary’s self-interest, and even then, knowing what we know now, it was extremely stupid in the long run.
