Why do celebrities say they "found Jesus" when they get in trouble?

Well, it appears that most of them will say anything EXCEPT "I was wrong and I did an awful thing." Michael Vick said he needed to grow up. That's easy for anyone to say. Most seem to have been instructed to say the "magic words" that will calm down all the bad publicity. I think very few ever think what they did was wrong. Most only regret getting caught.
