I bet he does not even have cancer
I have my doubts too. At minimum, we now know the dire prognosis was bogus. Not that it comes as surprise. The whole justification for his release on compassionate grounds was based on the say-so of one, unnamed doctor, a general practitioner--against the opinions of 4 specialists who refused to concur with the prognosis. (One wonders if the doctor wasn't named because doing so would reveal certain, um, affiliations.)
In Aug, 2009 Megrahi's prostate cancer was declared to be "very advanced and aggressive", declared metastatic, having "spread to his bones." His life expectancy was down to "months or extended weeks; certainly not into next year".
So this guy whose cancer was so aggressive that he was declared "certainly" DOA by 2010 is now gonna be around 5 more years. I have no doubt that when 2015 rolls around, he'll still be "terminal," with new, equally baseless timelines proffered for his demise.
The justification for his release is gone. It should be rescinded. Of course, now that he's in Libya, good luck with getting him back, suckas.
