Just a knife...knifin' around...cut cut cut

Managers at the Federal Air Marshal Service regularly made fun of blacks, Latinos and gays, took taxpayer-paid trips to visit families and vacation spots, and acted like a “bunch of school kid punks,” current and former air marshals tell ABC News.

One supervisor was even photographed in 2006 asleep on a flight, carrying a loaded pistol, the air marshals said.

In interviews to be broadcast tonight on “World News with Diane Sawyer” and “Nightline,” the air marshals describe a culture of incompetence, bigotry and sexism on the part of senior managers at some offices that has endured for the last decade and raises questions about the professionalism and performance of the force entrusted with preventing acts of in-flight terrorism.
