I didn't say this one was. But a riot on Tuesday could very well mean that things are going to ramp up from there the rest of the week. What if something happened at the concert? Or what if the campus police had to respond to something to help out the APD, and they injured/killed someone? This is a powder keg of potential liability for the university. Whether or not it's the right choice, they would look insanely irresponsible if they didn't do anything and something happened.
Leath can't do anything to stop the house parties and parties on Welch. But he can do something to stop the reason why all of the house parties are happening on the same night. And so he's erring on the side of caution after someone nearly lost his life.
I think we're going to have to agree to disagree on this one. Cancelling the real VEISHEA will not stop the house parties. Quite frankly, I'm concerned that now that there are no activities for distraction, the house parties will be worse. People are not going to go back home just because the sanctioned events are cancelled; more likely this will just send many of the people who would have been at those events over to the house parties.
