I don't see the connection

I believe something like four or five people have been convicted of drawn pornography in the United States - regardless, what does that law have to do with minor characters in games? Unless they're sex games what does one have to do with the other? And I haven't come across anything suggesting this law is being enforced more harshly. Of the few cases where someone was actually convicted, in most/all cases either there was suspicion of (real) child pornography which led to an investigation, or the person in question violated parole.

What's the name of the man who served time in prison for a hand drawing?
