There's a big difference between going to a camp that teaches military-type training against an unknown unnamed enemy, and one that teaches methods for attacking and killing civilians, especially a certain type of civilian, namely anyone who isn't your own kind.
You can send your kids to Ted Nugent's Kamp for Kids, your kid can join the Boy Scouts, your kids can attend hunting camps where they learn to shoot shotguns & rifles and archery. But I'll bet none of those camps teach a kid how to ambush and kill a civilian in their car.
Personally I think an anti-terror training camp for kids is a great idea. If I had the seed money I'd go for it.
I like your camp idea.
Always thought that government schools should include para-military training. When the student graduates HS, he shoud have completed the equivalent of military basic training, with a grade. Recruiters should be invited to attend graduation...
