I don't really think that was what Karol Sikora was doing though, to be fair to his detractors. (I have memories of him as a well-respected expert, from many years ago. Either he has changed his approach as he became more senior, or I was mistaken in the first place.)
Look at his involvement in the case of Lisa Norris
That is absolutely classic "hired gun" behaviour. Oh, you think the radiation overdose killed your little girl? Yes, I can go along with that, here's an expert witness report saying so. Then they get to the point where the experts from both sides confer to try to reach an agreement, and he realises he's not on solid ground at all. He revises his report to be less certain than it was originally, and the case collapses.
It's not really, consciously dishonest. It's unprofessional. It's an outlook that aligns itself too closely with the side of the dispute you're talking to, and fails to take a properly professional, unbiassed, disinterested view. I've seen it scores of times in the witness box, often from senior academics.
As y'all know, I'm a big fan of David Colquhoun. What David has to say about Karol is quite distressing.
I happened across this lot after I'd posted my out-dated opinion about Karol Sikora being a respected expert. He may have been at one time. Now he's something else.
Which is actually fairly peripheral to the Megrahi affair. In that situation, all parties involved in the decision were aligned in their wishes. Libya wanted their human sacrifice home, being as they didn't believe Lockerbie was a Libyan operation in the first place and had only agreed to pay compensation for political advantage. The Westminster government wanted him home to get rid of this perennial bump in the road that was complicating their oil deals. And the Holyrood government wanted him home so they could get that appeal stopped. Having Megrahi die in a Scottish jail was also politically unacceptable, as it would have done lasting damage to UK/Middle Eastern relations.
In that situation, just who was paying whom to come up with an agreeable opinion really isn't all that important.
