Sorry, I disagree with that assessment completely. I think those people have every right to release their pent up fears and anxieties. And for once, we actually got the bad guys, even if the circumstances weren't as heroic as we would have liked.
How does this amount to a raucous celebration? If they all went to church and prayed for two hours I could see it, or you know, a candlelight vigil, or something along those lines. A New Year's Eve celebration, I just don't get.
