To me, the root problem is that the 'justice' guy was regarding anything supporting the mass-murderer's release as being good, anything impeding that release as bad ... shouldn't anyone in that position be at least neutral on the question of release, rather than wanting a reason to release criminals if he can? I'm not alone in suspecting he never really put his previous career as a defence agent behind him.
Yes, Megrahi will soon die - as he was "supposed" to almost two years ago now - which will at least bring a little closure. I would hope this debacle has at least made this government less trigger-happy about letting convicts out - perhaps amend the law to exclude violent crimes from the scope of this early release loophole, and/or change it to a tagging-based home release, with a curfew and absolute prohibition on leaving the country. As it is, even after Megrahi violated the conditions of his release (regular checkins and notifying the authorities of any change of address), was there really any chance of the Libyans returning him because of it?
Of course, bringing back capital punishment and applying it in his case would have avoided the whole issue - though sadly the promising start that e-petition had seems to have stalled now, and our politicians are probably too soft to comply anyway.
