The last time I looked, bin Laden isn't a citizen of the USA, and neither are his top officials, or those who maned the planes. There are some citizens, who have gone to fight with bin Laden, but hopefully, they have been killed already. What they did, is TREASON !
George Washington, as president , had a military tribunal for those who were traitors during the Revolution, Lincoln also instituted such trials, as did FDR. This president has been set 100's of years ago. For all of the people screaming about wanting to go back to what the FFs would have done today, WE JUST HAVE !
