"Oh yeah...I had a great time this weekend and want it to continue...let's smash on someone's artwork!"
Does that sound very intelligent to you? Really? Because it sounds fucking MORONIC to me.
Have you ever heard of leaving to go to an after-party? Motel party? Hotel party? Campground party?
Look...a cop comes into a situation like that...they've been asking the crowd to leave...the crowd is escalating...getting louder...more crazy. You want 'em to wait? Don't wanna get maced? Don't act like a cock (or hang out around people that do). It's not difficult.
Like I said, I've been to every single Coachella and NEVER ONCE had a problem. It's called acting with some common fucking sense & decency.
People like this are the same sort of people that got alcohol banned on all public beaches in San Diego because they don't know how to fucking act like grown-ups. They have to go and fuck things up for everyone else.
Personally I blame it on the spoiled-ass "mommy & daddy will fix all of my mistakes for me" society that we're trending towards. But that's just me.
