DS are not allowed to physically abuse them? But they do. In fact I have several friends that were raped in boot camp situations, male and female. Tell me that is not abuse. The rules may officially say abuse is not allowed, but it happens anyway, which is why I find boot camp situations to be abusive. I also find the way DS yell to be verbally abusive.
And I can assure you that none of my friends came out of boot camp a better person. In fact most of them just had more anger towards society, and most of my boot camp friends are no longer communicating with their parents because they feel the fact their parents put them in that situation is unforgivable. As for their respect for authority--it has only decreased. My boot camp friends have learned that "authority and respect" justifies abuse. That under the name of "authority and abuse," things like rape and physical abuse happen.
So that is why I don't think boot camp is a solution for troubled teens. If anything, it only makes them more troubled.
