There is no justifiable reason for charging people to look at scantily-dressed young teens. You can twist it using justification but in the end, we all know what is happening. We need new laws when the pedophiles use loopholes to escape the old laws. The problem in this country is NOT too LITTLE pedophilia. It is too much. Allowing children to be used for ANY sexual purposes including sexual modeling is only going to increase sexual crimes against them.
Exactly. And pictures of scantily-clad young teens do not CAUSE crime, either. They are, perhaps, a contributing factor, although I somehow doubt that:
(a) an otherwise normal citizen with no history of pedophilia will suddenly decide to molest a child because he sees a provocative photo, or
(b) a pedophile will decide NOT to molest a child because he can't look at provocative photos of children online anymore.
In fact, the incredibly unlikelihood of option (b) is why I see no reason for a law here. Stopping this admittedly disgusting practice will do absolutely nothing to stop violent pedophiles from harming children.
