Query: Tim Matthews up to tricks - beware

Tim Matthews' UFO Revelation is tired and dated rubbish - but it is part of a clever strategy to infiltrate the UFO movement. Tim Matthews was/is Tim Hepple, violent thug and fascist sympathiser. His work for the MI5-backed Searchlight organisation (who are connected to the British state - see the infamous Gable memorandum)involved infiltrating and disrupting left wing, anarchist and green groups - see the work of Larry O hara and others in the excellent magazine Notes from the Borderland and the pamphlet At War with the Truth. Available from AK Press. Ufologists should check this guy out as he is up to no good and his writings and interventions, including UFO Revelation, are all part of an elaborate disinformation and entrapment campaign organised by people far cleverer than this dupe. Beware. Keep your distance and be careful about Matthews/Hepple. Watch out for further revelations on this author in the near future. We are many, they are few.
