As a Scot, I am somewhat perplexed by the letter-writing of FBI [Director] Robert Mueller, who strongly voiced his opinions regarding the recent release of the Libyan bomber [of Pan Am Flight 103] (“Scotland defends bomber’s release,” article, Aug. 24).

I understand Mueller and his frustrations because, like him, I believe those serving a sentence for crimes against humanity should only be afforded the compassion they showed their victims ... very little, I would wager.

But Mueller, before planning some dastardly deed against the people of Scotland by way of retribution, should think of how the people of Vietnam felt when the U.S.’ own Lt. William Calley, who was found guilty and sentenced to a life term for his part in the coldblooded slaughter of some 500 men, women and children, had his sentence reduced to three years of house arrest — surely no better than the ridiculous compassion shown to the Libyan fellow.

It brings to mind the adage about not throwing stones while one lives in a glass house.
