I read that some (maybe most?) of the occurences happened in West Campus area. I lived there when I went to UT a couple of years ago and there are quite a number of frat/sorority houses and it's an area of campus filled with students who like to party alot more.
It's sort of surprising to hear something like this happening but there are enough tools on that campus (and WC area) that I cannot say I'm THAT surprised. Its good to hear that students organized a rally to protest this sort of disgusting behavior. Well see what administration will do. I remember the law school doing almost nothing when some dummies had a racially insensitive party while I attended. I'm sure those kind of parties still happen at UT. Even though I'm an alum, I don't look at that school through burnt orange colored glasses sorry.
