Thomas Smart was convicted of possessing live ammunition following a bullet keyring being found at his home. The keyring was sent to the Government’s Forensic Science Service (FSS) for testing, and they concluded it was a live round. He felt forced to plead guilty to the crime. His conviction was quashed after the FSS admitted that the wrong exhibit had been examined.
“When forensics experts said it was a live bullet Mr Smart was forced to plead guilty to the crime and suffered depression and anxiety due to his arrest and wrongful conviction, judges were told.”BBC News
