I posted this elsewhere, but I do think it's relevant to the situation, given that Matt White was a wrestler at Iowa State: I'm not saying that Matt did anything wrong, (if what he said is true, he was in the right in every way) but I think it's worth mentioning: I've been around the ISU wrestling program for years, and there is a palpable hatred for the basketball program among a group of the wrestlers. Some of them still think Iowa State should be a wrestling school and don't understand why all our fans adore the bball players.
Again, not saying Matt White did anything wrong, as it sounds like BDJ was being a pretty crappy neighbor. But it could explain why the situation escalated to the extent that it did.
