Comment: I said this above, and I'll

I said this above, and I'll try and apply it to this situation. The ONLY situation where "IP" should be protected is in the event that someone purports to be a company that they are not. I cannot open a store with golden arches and call it mcdonalds if it isnt really mcdonalds.

Here...its more tricky.

If the guy is purporting the shirts to be something that is made or sanctioned by the NFL, then I'd say the NFL has a case. But if he clearly makes the claim that his shirts are not in anyway sanctioned created made or distributed by the NFL and that his shirt merely has the image of the saints on it...its hard to say.

But the theory I'm using is an application of a standard libertarian idea, that fraud is illegal.
