For the first time in three decades, the U.S. Supreme Court will consider changing how eyewitness evidence is treated by law enforcement and the courts. Each year, more than 25,000 eyewitnesses wrongfully identify suspects in criminal investigations. That has led to thousands of suspects who have been wrongfully convicted. A plethora of research illustrating eyewitness error has poured in from academia over the last 20 years. Still, the courts have yet to put the new knowledge into practice. In fact, judges, lawyers and jurors give more weight to eyewitness testimony than other trial evidence. In 1981, Justice William Brennan quoted a leading study that said there is nothing more powerful “than a live human being who takes the stand, points a finger at the defendant, and says, ‘That’s the one!’” Those words are backed up by numerous studies illuminating the significant sway eyewitness testimony holds over jurors. Still, researchers contend that the testimony – in all its power – is highly unreliable, especially when one witnesses a crime that occurred quickly. So what kind of witness IDs warrant a closer look by judge and jury? The Court will weigh that soon in Perry v. New Hampshire. How should police treat eyewitnesses right after a crime has occurred? What about when they’re looking at a line-up? Of course, some eyewitness testimonies are completely accurate, so how should such evidence be weighed at trial? What type of ruling from SCOTUS could clear this up in practice? Why aren’t judges doing it already?
