This is a pretty well-debunked canard. 1) The Taliban knew OBL was guilty since AQ had basically admitted it and whatever else you can say about them, they aren't stupid, and 2) their offer was to extradite him to a third neutral country --no candidate was ever named -- that would ostensibly put him on trial free of US influence.
The entire offer was absurd.
I got a star-shaped paperweight with my name on it together with 100 dollars worth of gift cards.
This for two years in a row, because everyone really needs two star-shaped paperweights with their name on them.
The truth of the above statement is borne out by its sheer pedestrian banality in the sense that it's not something anyone would ever bother to lie about.
The sad part about it is that I am a dues-paying union member. One can only imagine how much worse it is for the non-union blokes.
At least the union gives me a way to fight back and to have a little dignity and self-respect.
