During 1906, Heney prosecuted San Francisco Mayor Eugene Schmitz and political boss Abe Ruef, for bribery. Heney revealed that a prospective juror was ineligible because he was an ex-convict. The man deeply resented Heney's action and while court was in recess, walked into the courtroom and shot the attorney in the jaw. Heney survived the wound, and the trial went on. He ran for the US Senate from California on the Progressive Party ticket in 1914.
