The idiot judge who wrote the opinion reasoned that
the statute was intended to protect minors like appellant and her co-defendant from their own lack of judgment...
Appellant was simply too young to make an intelligent decision about engaging in sexual conduct and memorializing it. Mere production of these videos or pictures may also result in psychological trauma to the teenagers involved.
So, to protect her from "psychological trauma", we should lock her up and stigmatize her as a criminal. Remarkably, another judge agreed with this bullshit, producing a 2-1 opinion.
People like this not only shouldn't be judges, they shouldn't even be allowed to vote for their neighborhood association boards. Heck, they should be locked up, to protect them from their own idiocy.
