Yes, this is further confirmation of what has been fairly convincingly argued previously. Private Eye published a useful supplement on Lockerbie, and Lester Coleman's 'Trail of the Octopus' is worth getting hold of (if still available). Coleman was a DEA agent IIRC, he alleged that the DEA was permitting drug consignments from the Bekkaa Valley to bypass the normal airport baggage security checks at Hamburg, as part of their investigations to observe who would collect it at the other end. Unfortunately the bombers got wind of this scheme, and used it to get a bomb on board the plane without security checks discovering it. A member of this Bekkaa drugs cartel was related to someone quite high up in the Syrian Govt. again IIRC. (Also odd goings-on at the scene of the crash, where a Scottish farmer found a suitcase full of white powder; mysterious armed US officials taking over the crime scene investigation; and a UK doctor being told to alter the number of bodies he had found by one).
The initial enquiries suggested that the Iranians (who had both motive and money) had 'commissioned' the (Syrian-backed) PFLP-GC to carry out the bombing. But with a bcakground of the invasion of Kuwait and subsequent Gulf war, this was 'off-message', given that Iran and Syria, as enemies of Iraq, were both allies of the US. Presumably this is no longer the case!
