The role the jury trial plays in criminal cases is fundamental to the American scheme of justice.1 The right to a jury trial is rooted in our legal tradition2 and is articulated in the U.S. Constitution.3 This protection extends back to British common law, and serves as a check against government oppression by ensuring that a defendant’s fate lies in the hands of a jury of ordinary citizens rather than the government’s prosecutor or judge.4 Coupled with the presumption of innocence, the right to a jury trial serves as a “cornerstone of Anglo-Saxon justice”5 that limits potential government tyranny. At the heart of jury trial protections and the presumption of innocence lies the concern that it is better to let a guilty man go free than to convict an innocent man.6
