Treason?

I've not heard anyone mention this, but if Faisal Shahzad, the terrorist who set the car bomb in Times Square, is a U.S. citizen, shouldn't he have treason added to the list of charges against him?

And what about the news media who claim poor Shahzad was really a good person, but circumstances may have caused him to commit this atrocity. He lost his job, his home was lost to foreclosure, and he just didn't fit in. Well, maybe he could have made his house payments and kept his job if he hadn't been spending all that money going back and forth to Pakistan numerous times!
