Thanks, good point. Still, if they are under "official" cover, they may carry some kind of government ID, or access badge, or whatever. If they weren't under official cover, they may have simply been scooped up with the rest. Since they were evidently killing Americans as they found them, killing two Americans with government ID would be icing on the cake. They wouldn't necessarily know who they were or care.
I would be curious to know if the terrs did know, though, who they were from the beginning, and were in fact looking for them; that would imply ISI help with the planning.
But it may have been luck of the draw; if you attack the ritziest hotel in town, you can expect to get some big shots. Something like this was planned for a long time. It wouldn't have been contingent on those guys being there unless they regularly were there. And if that were the case, you wouldn't need an op this big just to get those two guys.
“But it may have been luck of the draw”
If in fact they were intelligence officers then it is likely just the luck of the draw. American Govt officials rarely follow the same routine every day so as to avoid being targeted. I also find it odd that anyone would know they were intelligence officers as opposed to just American diplomats. Not even our own government would out them after their death and since only two Americans (a father and daughter) have been ID’d has having been killed I think this story is likely false.
