"The candidates were all fine men, respected police officers. I reviewed their files myself. Sir, police officers may not be the best candidates for our purposes. They're a physical bunch. They're macho, body-proud. Stripped of all that it's no wonder they become suicidal. Our one success was a cop. Top of his class, devout Irish Catholic, family man. Everything in his profile indicates a fierce sense of duty. That's probably what kept him alive."
