Person of Interest

Person of Interest is an American science fiction crime drama television series that aired on CBS from September 22, 2011, to June 21, 2016.

The series centres on a mysterious, reclusive billionaire computer programmer, Harold Finch (Michael Emerson), who has developed a computer program for the federal government known as "the Machine", capable of collating all sources of information to predict terrorist acts and to identify people planning them.

The series raises an array of moral issues, from questions of privacy and "the greater good" to the concept of justifiable homicide and problems caused by working with limited information programs.
