Colin Gunn is one of Britain's scariest gangsters, locked up in maximum security prison for ordering the execution of two grandparents. In the last two months, he's been using Facebook to frighten and threaten his enemies, communicating with his 565 "friends" online. Gunn wrote in one message, “I will be home one day and I can’t wait to look into certain people’s eyes and see the fear of me being there.” Gunn's page was shut down after Britain's Sunday Times notified authorities.
