Honestly, whoever wrote the script had no clue about security protocols. The wife, talking about her husband's work to a foreign national? disclosing personal information about the head of MI6 to the CIA, along with a recording of a telephone conversation???
Many really dumb situations. Anyone that worked in corporate, or finance, knows the basic confidentiality protocol, what information to discuss, and what not to. The people behind this movie don't have a clue.
