I don't believe a word of this drivel. They SAY he was going to meet with Chomsky. They SAY he hated Bush. Any proof? Sounds like his mother is just a Cindy Sheehan-in-training. She, like Sheehan, does not honor his sacrifice with this crap.
The proof may have been in his journal that "disappeared". Produce the journal, and I'm sure we can clear up a lot of things. Still, it doesn't explain why his body armor and uniform were burned days after his death.
