Police interest in Lindsay's activities intensified towards the end of the seventies: his premises were raided several times and attempts were made to close Lindsay's cinemas on charges of "running a disorderly house". Undercover police officers had become members of Lindsay's cinema to gain evidence of this, in the hope of catching audience members masturbating. Lindsay alleges that an insider at Scotland Yard informed him that the police had been given orders to close his business down by all means necessary. In the early eighties, Lindsay had also begun selling compilations of his films on video, taking advantage of the then unregulated state of the British video industry, and selling them at £45 per tape through mail order (the tapes generally contained two or three films and uniquely, professionally made trailers for other Lindsay titles). Lindsay's Taboo video releases have since become collectors items and because of their scarcity are known to command high prices (a 1982 video of Betrayed and several other shorts recently sold for over £120 on eBay). In 1983, Lindsay's premises were again raided and he was sent to trial; this time he was found guilty of obscenity and served 12 months in prison. Lindsay alleges that the four videotapes seized that helped convict him were planted by the police.McGillivray, David 1992.
