Thanks to Phase4 for the response.  It is perfectly sensible to have a link to the Lord Advocate as he does have a role in the McKie affair. 

 I find the Lockerbie connection more iffy.  Phase4's first and second points only may be relevant but as he quite rightly appears to accept, they would require elaboration and preferably sources. 

 The fact that the Lord Advocate may have acted in a dodgy manner in one case to do with fingerprints does not seem to take us far in how he has dealt with other cases involving fingerpints.
