Does the impeachment-use waiver doctrine established by the Court in United States v. Mezzanatto, 513 U.S. 196, for plea-related discussions permit the government to introduce in its case in chief at trial a plea agreement signed by the defendant, thereby effectively presenting the jury with a written guilty plea entered without a Rule 11 plea colloquy, in the same way that the government may otherwise introduce a defendant's confession?
