The New York City Department of Health is responsible for the inspection of Manhattan restaurants to determine whether they comply with the city's health code. Forty-six of the department's inspectors were in- ducing restauranteurs to pay money to them for permit approval or for a favorable inspection. Is this activity a basis for a crime? What crime? What would a prosecutor be required to prove? Are the officers and the restaurateurs equally criminally liable? [United States v. Tillem, 906 F.2d 814 (2d Cir. 1990)]
