[329] Heney, on the eve of election, in reply to McGowan's argument that the bribe-takers should be prosecuted, effectively answered this contention. Heney's communication read: "To Frank McGowan, Esq. Sir: You are reported by the newspapers as having stated that you will prosecute the boodling Supervisors and that you will also prosecute Patrick Calhoun and the other rich bribers, and that you will grant immunity to no one. I invite you to answer specifically the following questions either in the newspapers or the next time you make a public speech: "1. If you prosecute Supervisor Lonergan (or any other Supervisor) for accepting a bribe to influence his vote in the matter of the trolley franchise, what witness, or witnesses, will you call to prove that he accepted the bribe? "2. Every child in town now knows that if Lonergan received the money at all it was from Supervisor Gallagher. Will you prove the fact by Gallagher? If you call Gallagher as a witness, how do you expect to induce him to testify without granting him Immunity? "3. When you prosecute James L. Gallagher for giving a bribe to Tom Lonergan or to any other Supervisor to influence his vote on the trolley franchise matter, by what witness or witnesses, will you prove that Gallagher paid the money to Lonergan or to any other Supervisor? Will you call Lonergan or any other Supervisor as a witness, and when you call him, how will you induce him to testify without granting him immunity? "4. By what witness do you expect to convict Gallagher of giving a bribe, or Tom Lonergan, or any other Supervisor of accepting a bribe in the matter of fixing the gas rate, or in the Home Telephone Company franchise matter? "5. If you prosecute Ruef for giving money to Gallagher to distribute to the Supervisors to influence their vote on the trolley franchise, by what witness, or witnesses, will you prove that Ruef gave the money to Gallagher? Will you put Gallagher on the stand to prove it, and if so, how will you induce him to testify without granting him immunity? Will you put Ford on the stand to prove that he gave the money to Ruef, and if so, how will you get him to testify without giving him immunity? Will you put Fat Calhoun on the stand to prove that he gave the money to Ford to give Ruef to give to the Supervisors, and if so, how will you induce Pat to testify without giving him immunity?
