JustPiper, I read articles on this kind of thing years ago, before the internet, so I doubt I can find any links. Anyway, these ideas for children resisting kidnappers are based on feminist ideas for how women should resist rapists. There is no body of evidence indicating it works for kids. Even if the teaching is right, studies of these programs showed that the children wildly misinterpret what they are taught.
I want the kidnappers to be scared, not my kids. This kind of program is just going to create fear because sensible children will know full well that they can't fend off an adult. Freepers of all people should know what it takes to deal with this kind of person (hint: 2nd amendment).
