Given his history, none of this is really that surprising. I think many people suspected crimes involving children were the cause of Josh's arrest before the charges were announced. Besides, doesn't it seem that the hardcore "family values" types are the worst?
There's always one of them arrested for something, be it child porn, underage hookers, getting busted at illegal massage parlors or with a male sexual partner after years of being publicly homophobic.
The more one screams about family values, the more I raise my eyebrows. Josh Duggar being a prime example.
