Yeah, I agree that the punishment should fit the crime in this instance. I'm not advocating more senseless violence, but harsh legal penalties should be brought against them. Their age makes little difference to me, they willingly tortured a person over some ignorant cause, and for that, they shouldn't be allowed to forget their crime. If I were to beat the living shit out of someone in my house, all over some silly dispute, but I did it with intentions of preventing her from leaving (kidnapping), and with full intentions of displaying my bravado and malicious intentions on the internet, then I'd expect a harsh penalty to be brought down on me. (Damn, that was a long sentence.) Anything otherwise wouldn't be very fair to my victim.

Either way, these brats need more than a slap on the wrist. They need a big slap of reality, so they'll realize that they may have just royally fucked their lives up over something trivial and stupid.
