Faith as an excuse for crime.

Brian Mitchell is being accused of kidnapping Elizabeth Smart at the age of 14 and taking her across state lines for sex. He says that he was given visions from God to do these things. His lawyers say his religious beliefs were delusions, that their client was insane and therefore cannot be held responsible for his actions. I personally feel that this is questionable, and that its more of a scapegoat for men convicted of serious crimes. Unless medical proof is provided that he really was insane before kiddnapping the girl then I feel that the excuse should be discarded and should be held resonsible for their actions.
