David Whelan is a documentary filmmaker and writer who has for the last three years researched the assassination of John Lennon. David is back to discuss the release of his book "Mind Games - The Assassination of John Lennon" and some areas in the case that we never got into such as Jose Perdomo and Milton Kline who is recorded in a documentary about MkUltra on how to create a patsy within three months and surprisingly visited Mark Chapman in jail.
