At last Ive gotten around to watching this famous older film.  It is of interest both as a piece of art and a piece of history.  In the argument over whether or not the media prompts violence, it surely must still be of interest that the film depicts De Niros taxi driver as developing the notion of killing the Presidential candidate and rescuing the young hooker Jodie Foster, and that John Hinckley subsequently tried to assassinate Ronald Reagan to prove to Jodie Foster that he loved her.
