That seems to be in favor of Zero Tolerance as the only way to remove emotions. Sort of Scotty vs Spock - unless we get Vulcans to make the decisions, emotions will way in.
Yeah, plus pointing out I'm wrong at the same time.

The problem is, we have rules and laws made with emotions. Even if enforcing them is dispassionate, it gets frustrating. However, I don't have... the language to describe it entirely. I think the rules we made, such as ZT toward weapon in schools, as they stand today, aren't the right answer. But, I can't honestly tell you what the right one is.
I prefer punishments come from actions, not thoughts or situation. I think people should practically be crucified for driving drunk, but not punishing people for drinking. Likewise, I think people should enjoy whatever porn they want, be it violent, child, or even animal, as long as they don't actually hurt anyone. I don't think a teenage girl grabbing a picture of her breasts in her bathroom is grounds for being a registered sex offender for life. She didn't hurt anyone by taking them, but some feels that just their very presence breeds horrors.
Of course, if you wander through 4chan's /s/ channel, you see a LOT of them. Obviously the laws aren't stopping from people making or posting them. I can't tell you if someone is sixteen or nineteen; I never could. Hell, I have trouble with most things from 15-25 which is a pretty big group.
I think tolerance is an important aspect of the laws. I think there needs to be built-in discretion by those in charge, but I think they should have transparency. If you have a rule about no weapons, then instead of a zero tolerance, go with a low tolerance and document it. Find out if there is a systemic case for bigotry in the system. Then, respond to that statistics. True, people could "play" the system, as it were, but I think it would be better than ZTZD (zero tolerance, zero discretion).
