I recently watched a documentary about Grace Millane called "The Lie". Grace was murdered on a first date by a man she met on Tinder. The majority of their date was captured on CC TV. The documentary was extremely harrowing to watch and incredibly sad. Grace was an intelligent and independent women but the man was a practiced liar and con, she didn't suspect he was violent and dangerous. For those using OLD please be careful and take your time getting to know strangers, they only reveal themselves gradually.
