Even he would say that he was not innocent of morality. He did something he shouldn't have. He talked dirty online to kids who he thought were his age. Then went to meet them. He thought they would be having some kind of a sexual experience together, but the fact that he made plans for later on in the evening with friends is evidence that he did not plan on participating. Stupid, immoral. But not worthy of six months in jail.
If these were cops, they made sure that he knew the age of the girl. I'm guess they had him dead to rights and momma ain't trying to hear that
