The real reason?

The idea that the Scots are either more compassionate or more reckless than anyone else in the West is one of the most comical I've ever heard, whether it's being advanced by the Scottish government on the one hand or the US FBI director on the other.

Consider two things. First, under devolution, Scotland has the opportunity to make all of the idiotic mistakes of a major power without the consequences. That's the nature of devolution. It's rather like Kentucky having a foreign policy. Second, Scotland is full of, well, Scots. Do we think for a minute that the Scottish government really want to be saddled with the cost of caring for a dying terrorist?

I rest my case.
