I very much enjoyed reading "Tales of the Stakeout Squad", but all should read the book Jim wrote himself : "Guns, Bullets, And Gunfights: Lessons And Tales From A Modern- Day Gunfighter".
Cirillo's opinions are important for a reason. He was an intelligent gun-guy who studied ballistics, handoaded, hunted, and was an all-around enthusiast. Unlike most, he was also an experienced real-world gunfighter who came in first in numerous high-stakes shooting competitions. His assesments of traits to look for in a person recruited for stakeout duty is fascinating on many levels.
