Continuity mistake: As the MVD and FBI are together watching the footage of the torture and interrogation of Politovsky, Witherspoon has his hand up on his face. The camera cuts to an angle from behind everybody showing the screen and now his arm is down. It then cuts to a closer shot of him sitting beside Preston and his hand is back up again on his mouth. (00:18:20)
Answer: It is stated that the FBI is working with their Russian equivalent, the MVD on a joint operation. The FBI primarily focuses on domestic issues but does on occasion engage in operations outside of the United States with the assistance and in the aid of foreign governments. The CIA would not be the appropriate government agency to handle the operation in the movie because that mission is a law enforcement operation. The CIA is strictly an intelligence gathering organization with no law enforcement authority.
