Plot hole: When the CIA detects that Matt is accessing sensitive information to track Frost, they trace Matt's location and find out that he is using a public computer in a cafe. We then see that Matt is viewing the same kind of software, files, etc. that the CIA views at their agency. There is simply no plausible way that a random public computer would have CIA software, or be able to access CIA data at all, regardless of Matt's clearance. The computer itself would have to be on a secure domain.
Safe House (2012)
1 plot hole - chronological order
Starring: Denzel Washington, Ryan Reynolds, Robert Patrick, Vera Farmiga
Other mistake: The caption onscreen when the C.I.A. Headquarters are shown reads "Langely, Virginia". It should be Langley. [Might be Netflix only].
Matt Weston: How am I supposed to get more experience by staring at four walls all day?
Question: In the second safe house, the dialogue that takes place in the kitchen - how did Matt guess the housekeeper was not to be trusted? (01:00:00)
