His first book, One Time: The Story of a South Central Los Angeles Police Officer, Bentley graphically depicts his involvement in suspect beatings and describes in detail the gratification he and his partners received from their actions.

During eleven hours of interviewing, Internal Affairs sergeants advised Bentley that he would be fired and prosecuted if he admitted to witnessing corruption or misconduct by his coworkers.

Bentley had no choice but to sign a statement and verbally deny all knowledge of police corruption in the LAPD.

Coincidentally, Bentley was a coworker and friend of convicted bank robber and Rampart police officer David Mack.

Bentley has defended Officer Kevin Gaines who was accused of corruption in the Rampart Scandal, claiming he was unfairly targeted by investigator Russell Poole.
