why didnt griminski(spoilers)
so the cia and fbi and white house were all aware of the brief. at the end when darby asks denton, the head of the fbi, who killed the man who masqueraded as the fbi friend, he said that is was really the assasin khamel and the killer was an operative hired independently by the cia.(rupert) when asked by graham why he was following darby, denton replies that the brief "initially scared griminski[the head of the cia] more than the rest of them and he sent rupert to watch darby and to protect her.
there is also a scene about half way through the movie when the cia, including griminski is watching darby at the hotel. they state that "they're looking under rocks, shes using credit cards, she'll be dead in 48 hours" and then griminski says "i guess this means that little brief of hers, is true after all"
so, at this point griminski believes the brief to be accurate and darby to be in danger. so right there the head of the cia, with support is within 100 feet of darby.
my question is this: why didnt griminski just send his agents over there and grab darby. they could have easily gone into her hotel room, surrounded her with agents and guns and said 'hey we're with the cia, we're going to take you in and protect you." then take her to a secure location until everything else is sorted out? why leave her out in the open when they knew she was in danger and correct in her assumption about the justices?
