The thread on capital punishment, got me to thinking that in my work ive met some pretty nasty people but only once could i say that i have faced pure evil. In 1989 in a professional capacity i sat oposite serial killer Denis Nilsen for an hour. Never have i seen such empty souless eyes, in fact as eye contact was integral part of my work i can safely say that it was the most uncomfortable moment of my life. Have never forgotten it...brrrrr
