its odd but when I was at Uni back in the early 80s I read a biography about him...think it was called High Times or something similar. It was like the first two thirds of the Mr Nice book, but had a lot more detail about the MI6 and IRA madness, and stopped after he walked out of his Brit court nick because he claimed he worked for MI6. Mr Nice just skimmed over the 6 links, or pretend links. As he worked out they would never confirm or deny any involvement so he walked the court case...laughing all the way back to Oxford. It also had a lot more detail on madman Jim McCann.
Looked it up and cant find it....maybe its out of print now.
Hes a hero of mine. I once based a paper on why the drugs policy in the UK was so stupid on one of his essays on a legalised framework for weed distribution, (because it puts the dosh into the hands of organised crime) and cited Mr Nice as a source document (where he talks about the Afghani links between extremists and the drugs trade). Hes also written some convincing arguments for legalised medical weed which I cited. The point of the paper was that weed enforcement is money wasted, feeds crime rather than defeats it, and prevents its use for medical purposes.
My boss accepted it as a respectable first hand expert source.....just goes to show eh?
The end paper still got surpressed mind. It made too much common sense a colleage said, and Keith Helliwell threw a shitfit when he heard about it.
