That might have to do with the fact that only after the "compassionate release" turned out to be a sham, where those who released him were suckered into believing he is deathly ill, did people suddenly turn to considering whether or not he was actually guilty.
What GlennB said. It's not necessarily a shame to have been figuratively hiding under a rock for the past 20 years as regads this case, but to assume everybody else is in the same position is a bit silly.
Here's a link to an award-winning documentary (warning, film is over 2½ hours long, this isn't a YouTube clip) expressing massive doubts about his guilt. It was made in
1994.
The Maltese Double Cross. It wasn't even the first, but it's the earliest available online. Lester Coleman's 1993 book
Trail of the Octopus is another early starter. (Note, the indictment was only issued in late 1991.)
There are many other publications, both print and AV, which go into a lot of detail about the case even before the trial and express the view that the authorities have got the wrong man. For example
Silence over Lockerbie. And that's even before the CIA's "star witness", without whom the indictment would never have been issued in the first place, was exposed in court as a lying scumbag who made it all up for money.
Only a months after the verdict was annouced in January 2001, the official UN observer to the trial published
a withering critique of the proceedings as a blatantly biassed miscarriage of justice. The earliest independent publication detailing the unsoundness of the conviction that I'm aware of is dated just the following month.
The Lockerbie Trial: a perverse verdict. Paul Foot's famous analysis of the trial,
Lockerbie: Flight from Justice, was published a few months later.
Moving on, the SCCRC report into the outcome of the trial which detailed no less than six identified grounds for appeal, on which a miscarriage of justice was suspected, was published in 2007. (Most convicts would be ecstatically happy with
one identified ground.) Professor Robert Black QC started his
Lockerbie blog at about that time. I myself started my first JREF thread questioning the soundness of the conviction in 2007.
The dismay expressed at the compassionate release by those who had been following the case over the years was based on the fact that the ongoing appeal was dropped at that time (for no good reason anyone can explain). It was widely believed that the appeal, which was scheduled to conclude last February, would have resulted in the conviction being quashed.
So I don't buy the claim that this concern about his guilt is motivated by concern for justice. It's merely an excuse, an attempt to change the subject, by those who having enthusiastically supported his release on "compassionate humanism" grounds -- and having lectured everybody who doubted the wisdom of such an action for their "cruelty" and "backwardness" -- were exposed as naive fools, as not only his embarrassing continued survival but also the disgusting hero's welcome he got in Libya showed.
Skipping over your embarrassing misconceptions at the beginning of that paragraph, I'll merely point out that those who greeted Megrahi at the airport were welcoming someone they believed to have been unjustly convicted. In fact, they believed he was a "hero" for voluntarily surrendering himself to trial for a crime he didn't commit in order to bring to and end 8 years of US sanctions against Libya which cost thousands of lives.
You really need to get up to speed with some of this stuff before you make ignorant comments about the issue.
I doubt it. Since it isn't even remotely like you think is was, I seriously doubt whether any comparison you make is likely to be a valid one.
Given the motivation behind this change of subject, it is reasonable to believe the "serious doubts about his guilt" story about as much as to believe the "three months to live" story.
Go read (and watch) just some of the mountains of original documentation and commentary expressing these serious doubts which date from well before the cancer was even diagnosed, before you make such an idiotic statement.
