FBI Director Robert Mueller blasted Scotland's justice minister for releasing the Lockerbie bomber, calling it an act that "gives comfort to terrorists" all over the world.
Mueller sent a scathing letter to Justice Secretary Kenny MacAskill, who cited compassionate grounds in his decision to let Abdel Baset al-Megrahi return to Libya because he has prostate cancer and was given only months to live by British doctors.
The angry tone of the letter is out of character with the normally reserved Mueller, indicating his outrage is personal as well as professional. He also sent copies to the families of the Lockerbie victims.
"I have made it a practice not to comment on the actions of other prosecutors," Mueller wrote. "Your decision to release Megrahi causes me to abandon that practice in this case. I do so because I am familiar with the facts, and the law. ... And I do so because I am outraged at your decision, blithely defended on the grounds of 'compassion.'"
