A Political T-Shirt as Terrorist

I was reading on CounterSpin Central today, among other places, that the Department of Justice and the Department of Homeland Security have both logged a fair amount of Web time recently looking at sites that offer politically-oriented pins and t-shirts. Specifically, these sites offer material that is critical of this government in general or this administration in particular.

Do we really have the time, money, and other resources necessary to spend $12 million prosecuting Tommy Chong and then spend more money investigating people who make t-shirts that state Bush+Ashcroft+Rumsfelt=Axis of Evil? Is this really why we're going horribly into debt?
