So my topic this morning is on forfeiture of the confrontation right, which I think plays a central role in confrontation doctrine. And to try to present that, let me state the entirety of confrontation doctrine as briefly as I can. This is, at least, what I think the doctrine is and what it can be: A testimonial statement should not be admissible against an accused to prove the truth of what it asserts unless the accused either has had or will have an opportunity to confront the witness-which should occur at trial unless the witness is then unavailable-or has rendered the confrontation unfeasible.
