Josh Duggar has come back to his wife and kids, all better now apparently after his fall into sin and temptation weakness. The rehab centre he went to was one that claimed accepting Jesus as lord and saviour was fundamental to any sort of recovery.
So I guess he's done that and now things are just fine again.....
I think it was the statute of limitations in the state he lived that meant he couldn't be convicted of molestation. Would be a different story here in Australia where there's no statute of limitations for child abuse. They can go back literally decades (as they have with the odd Catholic priest here). Josh Duggar would very likely be in jail now if he was here.
