Fair enough. I'm not at all advocating the police being able to use however much force as they want, but from what I saw, tazing that guy seemed reasonable. Also, consider the fact that that video is just a few minutes long. There could have, and probably was, more going on before the video was filmed.
Yes, there probably were safer ways to get this guy to go away, but maybe the cops tried them, and the video doesn't show this?
All I'm saying is, that guy was an idiot, and he deserved to be taken down. I'm not at all saying that we should follow Nazi Germany's lead, and allow the police "full-reign." That's a shitty idea. I just have a problem with people who do illegal things, then bitch about the police being "oppressive", or whatever. Being in a college environment doesn't help, as I've heard countless stories from douchebag-types about cops being "unfair" or "ridiculous" in ruining underage drinking. It's simple...don't break laws, and the cops won't have a reason to use ANY amount of force. If you're being nice and law-abiding, and a cop does something, you have a reason to say those things. But if you're breaking a law in the first place, don't whine about the police when you're caught.
That's a bit off-topic, but I think it kinda applies here.
Also consider that, in a festival environment, what will happen if people see the cops just ignore and walk away from a drugged-up naked wizard? That seems to me to be a flashing "anything goes" light. Which seems like an awful thing, especially considering how much I imagine ALREADY does go on at a place like Coachella.
