Teacher David Arthur was set up and sold out to a Sunday newspaper over drug allegations by former broadcaster Jonathan Marshall, Arthur's defence lawyers told a High Court jury in Auckland yesterday. Arthur is charged with supplying P to four young people, a story broken on the front page of the Sunday Star-Times last year after reporter Amie Richardson, an acquaintance of Marshall's, came into the possession of a videotape shot by Arthur at his house allegedly depicting the young people smoking the drug. The videotape was taken from Arthur's Glen Eden home without his permission by two of the young people, William Barling and Alexandre (Sasha) Kouznetsov. Yesterday, the court watched an edited portion of this videotape. They saw Marshall, one of the four, parodying Queer Nation and broadcaster Mike Hosking, whom Marshall was sacked from Queer Nation for pursuing for paparazzi photographs. Three other youths were smoking a P pipe in Arthur's bedroom. Arthur describes himself on camera as a "f**ked up, drugged out c**t".
