Currently reading Albion Dreaming by Andy Roberts. Fascinating stuff, the book is a 'popular history of LSD in Britain' and is well worth the investment of time to read it. At p162, the background of one of the Free Festival Organisers, Bill Ubi Dwyer, is being described. Dwyer used to sell LSD at a club in Sydney called the Cellar, the book explains,
The police sent undercover officers to the Cellar but this did not seem to bother Dwyer. ...he was buying LSD directly from the police, who largely controlled the Sydney LSD trade at that time.20
R L S Jones, which gives many other examples of police corruption. I found the following particularly amusing,
"The other day a solicitor told me that some time ago one of his clients was busted at Terrey Hills for amphetamine possession. He was taken to the police station and the police officer behind the counter was the one who had sold him the amphetamines, so his case never came to court."
