I didn't read this whole thread, but "exploitation of a minor" could just mean he had sex with a 16 year old, who consented to this. Her parents didn't like it, and they charged him.
It doesn't mean he's a pedophile.
I'm not saying this is the case ... just pointing out possibilities.
Personally, I wouldn't do anything. When I look up my neighborhood online, it seems like this is the place for sex offenders. They seem to be everywhere.
And then there's all the weirdos out there that you don't know about either because they haven't been caught yet or because they haven't started yet. (Sorry to be cynical!)
Danger is everywhere, IMO. All you can do is be aware of it, and stay protected. There's a reason I have a GSD for a pet, have taken self defense classes, and am very proficient at the shooting range. I'm not paranoid ... I live without fear. But, I know the danger is out there, and it's better to be safe than sorry.
