There is a good reason Mr Warrens Co-author severed all ties with him and that is the same reason why Left at East Gate was removed from circulation after over 25 years in print. Its the same reason I contacted the defective detective Gary Heseltine in 2016 and the same reason Warren sent me death threats and a failed legal challenge.  
Mr Warren was found to be a storyteller and all his supporting evidence was found to be bogus. Warren and Heseltine both then set out to make Capel Green with not so diligent filmmaker Dion Johnson despite warrens story being completely dismantled after his own handwriting exposed all his fake documents and showed that items he sold at auction were not what he claimed they were. Mr Warren was selling items allegedly belonging to John Lennon but i assisted in getting the letters of provenance for these items which were in his own handwriting. Mr Warren also falsely  claims to be a 911 first responder and has been proven to be a fantasist.

Gary Heseltine, the ET ambassador for aliens in the UK was informed about Warrens unlawful actions on August 26th 2016. Still think Gary is a world renound ufo expert? No. He is milking the UFO subject and is dishonest with his followers.  Further information here:
