passage: The Confrontation Clause of the Sixth Amendment to the United States Constitution provides that ``in all criminal prosecutions, the accused shall enjoy the right...to be confronted with the witnesses against him.'' Generally, the right is to have a face-to-face confrontation with witnesses who are offering testimonial evidence against the accused in the form of cross-examination during a trial. The Fourteenth Amendment makes the right to confrontation applicable to the states and not just the federal government. The right only applies to criminal prosecutions, not civil cases or other proceedings.

Ex Output:
Yes
