Whether the prosecutor's elicitation of evidence through a colloquy with a venireperson violated the defendant's Sixth Amendment right to cross-examination and a fair trial, Fifth Amendment due process right, and multiple Federal Rules of Evidence

QUESTION PRESENTED 1. Evidence upon which the jury may rely in convicting a defendant must come through qualified sworn witnesses, not through a colloquy with a venireperson. The prosecutor in this case elicited evidence that a shod foot is a dangerous weapon through such a colloquy, and referred to this colloquy in his opening statement and closing argument. Did this violate the Sixth Amendment right to cross-examination and a fair trial, her Fifth Amendment due process right, and multiple Federal Rules of Evidence?
