A New York Times front-page news article reports, "One of the senior Manhattan prosecutors who investigated Donald J. Trump believed that the former president was 'guilty of numerous felony violations' and that it was 'a grave failure of justice' not to hold him accountable, according to a copy of his resignation letter."
The Fifth Amendment says "No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a grand jury." The Sixth Amendment says "In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the State and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the Assistance of Counsel for his defence."
Here Trump hasn't been indicted, hasn't been informed of the nature or cause of the accusation, hasn't had a trial before an impartial jury—and yet a prosecutor has been able publicly to declare him "guilty of numerous felony violations."
The prosecutor, Mark Pomerantz, wrote to the elected district attorney, Alvin Bragg, "Whatever the risks of bringing the case may be, I am convinced that a failure to prosecute will pose much greater risks in terms of public confidence in the fair administration of justice." If Pomerantz is genuinely concerned with "public confidence in the fair administration of justice," maybe he should have thought about it before publicly declaring someone, before a trial, "guilty of numerous felony violations"? I guess Pomerantz can say he didn't intend for the letter to become public, but even so, it's precisely this sort of thing that erodes public confidence in the fair administration of justice. If Trump hadn't become president, or if he had been a more conventional president while in office, no one would care whether he used overly optimistic valuations of his assets.
