In the 71st minute there is reference to blood diamonds from Cameroon. Diamonds from that country are not considered deserving of the term, unlike those mined during recent civil wars in Liberia, Angola, Ivory Coast, Sierra Leone, etc.
In the 75th minute, say "suffice it to say," a common mistaken spin on the expression "suffice to say."

At 11:50 and in several subsequent shots, Markham looks out in the dark from several windows in the room. A light within the room he's in lights up the white dress shirt he is wearing. He is extremely visible from the exterior of the building. Any competent shooter would never allow himself to be so easily seen under any circumstances, and the error is all the more greater when he remains well lit after he learns he is being targeted.
