The recent Jason Statham action movie Homefront has a lead character who used to be an undercover DEA cop, Phil Broker.
Phil has moved to some small town in the country so his daughter can have a better life and, presumably, he can get away from a dangerous career where he was associated with choices he didn't like (an early scene establishes his discontent with police overkill during an arrest).
One of the key early events in the movie involves a neighbor walking into his house (the door is open but Broker is out riding horses with his daughter). The neighbor is seeking trouble (perhaps stealing the family cat to traumatise Broker's daughter) but is able to stumble on an unprotected box file containing details of Broker's previous undercover identities.
What possible excuse or motivation can there be for Broker to have highly sensitive files at home and completely unprotected?
