Agreed.
The fact that the CIA director refused to make any reference to Boyle, the Canadian, who, clearly was part of the family, says a lot. In fact, it says very loudly, and skilfully (without causing diplomatic problems with their neighbour, Canada) that something seems fishy.
Every word in statements like this is selected with precision.
One interpretation:  the CIA has suspicions, but cannot prove -- yet -- that Boyle's intentions in Afghanistan were not as innocent as he telling the public.
