 Things got very heated at a town meeting over whether to renew the contract of Canton Police Chief Helena Rafferty. If you don't step down, shut your mouth, and have your family's mouths shut as well. Resident Kristen Anderson and others are outraged over the Karen Reed case and the case around Sandra Birchmore, who was allegedly abused by three Stoughton officers as a teen before her death in Canton, which a recent forensic analysis suggested was not a suicide. Protesters argue those investigations were botched.
