On a semi-related note. This whole devolution of the morality of British gangsters. By which I mean that prior they had a different set of moral standards, albeit very alien from conventional morality. I digress.

It remind me of the Melbourne gangland killings. A new breed of savage gangster motivated by the drug trade picking up at around the same time as what you guys are describing. Hell, it's happening all over really. The common denominator seems to be the narcotics trade.

Either these guys are dipping into their own supply. Or the money from drugs is so massive that it makes crooked guys do even more fucked up shit. Mostly cultural if I had to guess tho.
