Richard Alfredo "Bo" Dietl (born December 4, 1950) is a former New York City Police Department detective and a media personality known for contributing on the Fox News Network and the Don Imus Show. As of 2010 he serves as Chairman of the New York State Security Guard Advisory Council, appointed by Governor George Pataki in 1995.
After injuring his ankle in a skydiving accident, Dietl retired from the NYPD in March 1985 and went on to found Beau Dietl & Associates, specializing in corporate investigations for major international companies. Among his clients are Columbia Pictures, Coca-Cola, Grey Advertising, PaineWebber, Lehman Brothers, Bankers Trust and the Saudi Royal Family.
The Republican and Conservative Parties of New York State for the 6th Congressional District nominated Dietl for the U.S. Congress in 1986.
- The plot in Abel Ferrara's crime drama Bad Lieutenant is mainly inspired by Dietl's 1981 investigation of the rape of a young nun, however the similarities end there. Unlike the protagonist played by Harvey Keitel in the film, Dietl was not addicted to cocaine or an alcoholic during his tenure in law enforcement. Dietl played a role in the beginning of the film, as one of the investigating detectives.
