Arrested for wearing a T shirt?

Scott linked to this Yahoo News about someone being arrested in an American shopping mall for wearing a T shirt with the words "give peace a chance".

The fact that the mall owner is within his legal rights doesn't mean that he's not acting like a jerk.

It's cases like this that make me realise how much the 'utopian' society advocated by the more extreme libertarians would suck for everyone other than the very rich. When everything outside your own front door is owned by someone else, probably some faceless and unaccountable corporation, you'll be forced to obey someone else's stupid and arbitary rules the moment you step outside your front door. America's sacred 1st Amendment? Forget it!
