Sure, that's what the Supreme Court says, but that's in direct opposition to the plain text of the Constitution.

rticle 3, Section 2: > The Trial of all Crimes, except in Cases of Impeachment, shall be by Jury; and such Trial shall be held in the State where the said Crimes shall have been committed; but when not committed within any State, the Trial shall be at such Place or Places as the Congress may by Law have directed.

That doesn't say anything about the severity of crime or the potential punishment of the crime. It says "all Crimes".

Sixth Amendment:

> 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.

This also doesn't specify anything about the severity of the crime or the potential punishment.
