The spin is it that he was fragged. But comments on the story are already poking big holes in this.
A) The AP article says Tillman was telling a fellow Ranger to "stop sniveling" right before he died.
Commenter: Nor is it likely he was "fragged" because he was a bit too gung ho. All Rangers are gung ho.
B) With the change in the storyline from friendly fire to fragging, but restoring the enemy fire detail:
Commenter: if they were under fire, how was there no evidence of that enemy fire?
C) With fragging questionable, and enemy fire and friendly fire eliminated, a commenter posits:
The suggestion that his platoon or company had something to do with the opium trade is beginning to look a lot less fantastical.
By george, I think he's got it! I don't know if Tillman had any thoughts about the illegality of Afghanistan or Iraq wars. Safeguarding opium shipments, on the other hand, could cause some re-thinking.
