A man at a bar in Murrieta, California ribbed an off-duty cop that he 'suck[ed] at darts,' the cop, 42-year-old Dayle Long, reportedly responded by pulling out a gun and executing him in front of a shocked crowd in an incident one man described as 'the most horrific scene I've seen in my entire life.'
