As a student who attended the celebration last night, as others have stated, the whole thing was incredibly peaceful and "under control." That being said, from my perspective, it seemed that only about 1/4 of the students were there because they were genuinely patriotic and wanted to express their love of America. The other 75% seemed to consist of the "omg, we're totally rioting, lol" crowd, who were there more for the spectacle/party atmosphere than anything else. Again, this was just my perspective; others who were there, feel free to disagree.
Overall, I do feel agree with some posters in this thread that the over-the-top celebration did feel a little bit inappropriate. This is NOT because I feel any sympathy towards Bin Laden, rather, it just seemed like I was attending a sports rally, rather than a celebration of our country. In the end, as happy as I was when I heard the news, I felt like a more subdued "hand the ball to the official"-type celebration would have been more appropriate than the "Yeah, we kicked ***!!" celebration that I saw last night.
