Because, unlike what happens with copyright violation, students at Kansas University would at least be given due process and the right to a trial in which they could defend themselves if accused of murder.
Oh, and P.S., just like Josh's blog, if you're at KU and just read this, well, you're worse than a murderer, and under the rules of your University, your Internet access needs to be cut off. This page is, after all; under copyright. (For more info, see and click on the "Creative Commons" icon at the bottom of the left sidebar.)
Of course, if they abide by their rules, KU really out to shut themselves off from the Internet altogether. The fundamental protocols of the Internet (TCP/IP), after all, are designed in a "peer-to-peer" manner, and "peer-to-peer" software is evil and prohibited. This would be a nice solution; cut all of KU off of the Internet because the Internet violates their Internet policies. In any event, that's what their rules tell them they have to do. (And, I suspect that the RIAA and the MPAA would love nothing more than to see the entire Internet disconnected.)
It's just nuts how witch-hunty we've gotten about copyright violation. The slightest hint from the RIAA thugs that there's an issue, and you begin to wish that you were in Guantanamo Bay facing trial as an enemy combatant.... It's a wonder Cheny hasn't tried to harness the RIAA lawyer corps, for they seem to operate in a mode that plays to his heart.
