Does the Sixth Amendment give a criminal defendant the right to confront and cross-examine adverse witnesses?

"[T]he Sixth Amendment to the federal Constitution gives a criminal defendant the right to confront and cross-examine adverse witnesses." (People v. Lopez (2012) 55 Cal.4th 569, 576 (Lopez).) In Crawford v. Washington (2004) 541 U.S. 36, "the court created a general rule that the prosecution may not rely on 'testimonial' out-of-court statements unless the witness is unavailable to testify and the defendant had a prior opportunity for cross-examination." (Lopez, supra, at p. 576.)
