STATE OF TENNESSEE v. ARTHUR T. COPELAND is a May 2007 decision from the Tennessee Supreme Court, overturning its long-standing precedent excluding eyewitness testimony as common sense, citing (among other things) PDS (D.C.) poll data showing that jurors tend to overestimate the reliability of cross-racial IDs. The defendant in the case had been sentenced to death, but the Supreme Court overturned the conviction for the trial court's failure to admit the expert testimony of Jack Brigham on the cross-race effect.
