hmm wearing something like that to court should be illegal. I would see that as intimidating a witness. Selling it is about the same as selling a Che shirt.
Now you're being rational. Please Stop.
No one pretends that actions should be as free as opinions. On the contrary, even opinions lose their immunity, when the circumstances in which they are expressed are such as to constitute their expression a positive instigation to some mischievous act. An opinion that corn-dealers are starvers of the poor, or that private property is robbery, ought to be unmolested when simply circulated through the press, but may justly incur punishment when delivered orally to an excited mob assembled before the house of a corn-dealer, or when handed about among the same mob in the form of a placard. - J S Mill On Liberty
