When I worked in the mobile center there was a story: the wife of the divorce hired a private detective and he just went to the center, took and removed from the computer of someone in the office printed calls, including conversations with the mistress. I put it in court. The man was heated up for a small amount (why I don't remember anymore), and we had the passage to any department only on cards. This is a spy series.

Well, such a person came out of the street by chance, entered the computer under a password, logged in to the program, knew how to remove a call log, all this was copied to the flash drive, while the owner of the company did not come to his place. In addition, the court does not accept evidence obtained illegally, and he did not have permission.
