The Albuquerque Journal has an article about Second Chance, in which it claims that it was not just partially based on on Scientology, but that Scientology was its very skeleton.
I think this is very plausible. The president and her husband being Scientologists, and the program being funded in part by wealthy Scientologist such as Randy Suggs, a Scottsdale, Ariz.-based Scientologist businessman and part-owner of the Arizona Diamondbacks major league baseball team.
Unlike the "Study Tech", that could partially stand on its own (see Will Smith schools), Scientology does not mix well with other methods in such a field as drug and crime rehabilitation. You need to tackle with the root cause of these deep-seethed problems, and you can't really do that without addressing what in Scientology is considered as the prime source of what they call aberration. Other methods can come as a support to it, but I don't see how it could be the other way around.
This being said, it does not necessarily mean that the program is harmful or ineffective, and it seems that on the contrary it did have positive results, as I blogged about back in Dec. 30, but I agree that such an evaluation should be conducted through independent and objective means.
It is not going to happen anyway, because the mere link with Scientology is going to bring distrust to the program, hamper its government funding, and make it the target of close scrutiny for anything they'll do that isn't quite kosher. As it already happened, by the way.
