Looks like a legitimate drug bust to me. 3000 people versus a few police. I'd say going in hard with high shock value is a good way to make sure a large crowd cooperates.

I doubt the party was "legal" or they wouldn't have been able to get the warrants etc to call in that many resources.

I saw a story on 'raves' a while back on 60 Minutes or one of those shows. It has become a problem in some communities. Kids dying, increased crime in the area, etc. Maybe they decided to put their foot down in Utah. As long as they had proper warrants to make the raid, I got no problem with it. If they used excessice force then they should be held accountable too. Let a judge and jury decide.
