Reason 1: United States Attorney General Alberto Gonzales is trying to push that it's illegal even if you ATTEMPT to infringe on or pirate copyrighted material. Specifically music, since under this new push the Department of Homeland Security must give their findings over to the RIAA. Oh and you could be sentenced to life in prison.
Reason 2: You probably already are a terrorist. With the rush into the War on Terror, no one stopped to try to define what a terrorist actually is. However I dont think it's the immediacy that lent to us skipping over that bit as much as it is nearly impossible to specific label what a "terrorist" is. Well now the FBI and some states have their own meanings, and you are probably on their list.
Reason 3: Karl Rove is using the office of the President of the United States to subvert justice right here at home. But as Gonzales concedes now (now that he can apparently remember again) that his former Deputy was the real guy that was to blame.
