I don't get where you'd get the idea that any rights would be violated if they have restrictions in place on when certain spaces can be used. Doesn't just about every metro park have a closing time?
That's basically what was going on here. They were camping out in a space, and there was no specific regulation saying "you have to leave this space by 6PM" or something to that effect. Thus, when the idiots were removed from that space, the judge says, it wasn't proper because there was no stipulation that they would have to leave by a certain time. So now, there are specific times when you can be there and when you can't. Nobody's rights are violated, nobody has a right to be in whatever place they want whenever they want without restriction.
