Whatever are you talking about? I think this is a great set of tips. I constantly drilled things like this with my kids when they were growing up. Constantly. There are some here I didn't ever think of, though.
Too many parents today are sooooo complacent in this stuff. I always told mine to make as much noise as they possibly could. Kick, scream, bite, poke them straight in the eyeballs. If a man, kick him or punch him as hard as they can in the crotch. Scream "this is not my daddy!" or "this is not mom!"
I can't imagine what you're calling nonsense; I think every parent should go over things like this with their kids OFTEN. Perhaps it's not scientific enough to suit you, but most of this stuff is pure common sense.

Yes. It is common sense. Carlie's mother said that her daughter would do everything possible to get away from Smith. I believe her, but common sense to me is that a child against planned out pure evil in an adult is an unequal struggle. It looks like he tried at least once before to kidnap a woman, and failed, and so decided to use his "great with kids" skills to single out a victim he could succeed with.
