Each city and county in the Metro service area has similar ordinances that regulate or prohibit vending on Metro-owned property, and which prohibit riders from eating, drinking, or smoking in Metro trains, buses, and stations; the Transit Police have a reputation for enforcing these laws rigorously. One widely publicized incident occurred in October 2000 when police arrested 12-year-old Ansche Hedgepeth for eating french fries in the station. In a 2004 opinion by John Roberts, now Chief Justice of the United States, the D.C. Circuit Court of Appeals upheld Hedgepeth's arrest. By then WMATA had answered negative publicity by adopting a policy of first issuing warnings to juveniles, and arresting them only after three violations within a year.
