Precinct on the Hill: Policing Congress, Prohibition, and the Man in the Green Hat

Part of A Dry Hypocrisy Series...forgotten true stories of power, privilege, and unequal enforcement in Prohibition-era Washington.

Who polices the lawmakers when privilege stands on the other side of the door?

During Prohibition, the United States Capitol was both a symbol of national law and the workplace of officials who quietly violated it. Through its entrances moved senators, representatives, employees, visitors and George Cassiday; the bootlegger whose familiar face and carefully managed deliveries became part of congressional routine.

Guarding this contradictory world was the United States Capitol Police.

The Precinct on the Hill: Policing Congress, Prohibition, and the Man in the Green Hat, examines the institution caught between public law and legislative privilege. Officers were expected to protect Congress, preserve order, recognize familiar faces, and respond to threats. But what happened when the protected institution became the setting of the violation?

Cassiday's 1925 arrest, his move from the House to the Senate side, the undercover operation that penetrated his network, and his final 1930 capture reveal a fragmented enforcement system in which familiarity could become camouflage and jurisdiction could become shelter.

This is not a tale of a fictional police conspiracy. It is a true, documented, examination of institutional boundaries, divided authority, selective visibility, and the dangerous distance between guarding a government and holding it accountable.

The officers remained at their posts. The doors remained guarded. Yet for years, the illegal trade moved through the corridors they protected.
