While the Knapp Commission began its investigation of corruption in the police department in June 1970, public hearings did not start until October 18, 1971. In addition to the testimony of "lamplighters" Serpico and Durk, testimony from dozens of other witnesses, including former Police Commissioner Howard R. Leary, corrupt patrolmen, and the victims of police shakedowns, were heard. From 1970 to 1972, Michael F. Armstrong was chief counsel to the Knapp Commission. Nicholas Scoppetta served as associate counsel. As an immediate result of the testimony of the witnesses, criminal indictments against corrupt police officials were handed down. Commissioner Patrick V. Murphy was appointed by Mayor Lindsay shortly after the commission was formed to clean up the department, implement proactive integrity checks, transfer senior personnel on a huge scale, rotate critical jobs, ensure sufficient funds to pay informants, and crack down on citizen attempts at bribery. On June 15, 1972, Whitman Knapp, Chairman of the Knapp Commission, was nominated as a federal judge for the Southern District of New York by President Richard M. Nixon.

"Grass Eaters" and "Meat Eaters"
The Knapp Commission Report on Police Corruption identified two particular classes of corrupt police officer, which it called "Grass Eaters" and "Meat Eaters". This classification refers to petty corruption under peer pressure and aggressive premeditated major corruption. The term "Grass Eaters" is used to describe police officers who "accept gratuities and solicit five, ten, twenty dollar payments from contractors, tow-truck operators, gamblers, and the like but do not pursue corruption payments". "Grass eating" is something that a significant number of officers are guilty of, but which they learned to do from other cops or from imitating the deviants they watch and investigate every day. The commission even concluded that "grass eating" was used by police officers in New York City to prove their loyalty to the brotherhood, and with that came incentives like side jobs. One method of preventing cops from becoming corrupt is to eliminate this step by removing veteran cops who do this; without any veteran cops to learn this from, new officers might decide to never "eat grass". "Meat Eaters" are officers who "spend a good deal of time aggressively looking for situations they can exploit for financial gain". An example of this is shaking down pimps and illicit drug dealers for money, not only for the material profit to the officers, but for the relief from guilt that the officers derive by convincing themselves that their victims deserve such treatment. They justify taking advantage of these kinds of criminals because they are considered the dregs of society.
