This isn't meant as rhetorical, and I'm not trying to score some point. I'm honestly not sure where I land on this. Part of me wants to say "tough noogies, it's worth it to stop those kiddie diddlers" and another part is going, "whoa nellie, what if most of those people are completely innocent but will now forever live with this awful stigma?"
I think there's a multi-track drifting joke in here somewhere too, but I haven't had my coffee yet.
