http://www.bbc.co.uk/news/uk-england-london-37358681 "A man has been stabbed to death while trying to stop a group of people from stealing a moped outside his home. The victim, named locally as Ricky Hayden, 27, confronted the four men in Chadwell Heath, east London, at 01:35 BST on Tuesday. He and his father both suffered knife wounds in the attack on Gibbfield Close and the son later died in hospital." I know it is a moped, but I own both cars and bikes, so it made me think, how far do you go? Especially after recent posts about people just walking in a unlocked door when people are about.
