Freepers of all people should know what it takes to deal with this kind of person (hint: 2nd amendment).
I am very pro-2nd amendment. Life NRA member, annual contributor to CCRKB, SAF and others. Have concealed carry in two states, etc., etc. When it comes to 2nd amendment you are preaching to choir here. BUT, children cannot legally carry.
I want the kidnappers to be scared, not my kids
This sounds so PC it is astonishing but perhaps I am misinterpreting what you are trying to say. Kids should be scared of kidnappers. So scared that their adrenaline kicks in and they fight and scream with all their might. Would you rather they didn't fight for their lives at all?
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 understand you read this along time ago and cannot find the links. But, if these "studies" were valid I feel quite certain that they would still be out there for you to find and post or similar studies with similar results to back up your claim would be online for you to post. Until then I'm not buying it. As far as "children wildly misinterpret what they are taught" I give the average child a lot more credit than you, or these "studies" do. Children, taught properly, can learn anything whether it is math, english or self-defense techniques. Children, given half a chance, crave learning. It sounds to me like you want children to be defenseless and helpless which does not need to be the case.
