The sixth amendment to the u. s. constitution begins: “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…” what does this mean in practice for a defendant in a federal criminal trial?

jurors that represent different types of people in the community are more balanced when making a decision.
unbiased jurors are more likely to come to a fair decision in the case.
a jury must be a group of people who know the trial process and the law.
the jury must decide a case quickly, so the defendant doesn’t have to wait long for the verdict.
