I started a discussion on my blog regarding Nigel Haskell, the employee at McDonald's who was shot after removing a man from the restaurant who had just hit a woman.
What a story. It's refreshing to see someone who has enough guts to stand up for a complete stranger. It's also a demonstration on the law of unintended consequences. This story can serve as an exercise we can all learn from. Calling 911, de-escalation techniques and situational awareness might (or might not) have led to a different ending.
