The shooting this morning near the Empire State Building reminds me of a recent conversation that I had with a former San Diego police officer about watching a fight unfold right in front of you. Many people have had the experience at some point in their lives, and if you ask people about it, they can tell you all about what happened before the fight broke out. They talk about the aggressive person getting into the face of the person they are about to fight. They talk about the aggressive person taking off his shirt or hat before the fight begins. They bring up the fact that they watched the aggressive person approaching or running at the person he was about to strike. And they bring up every other pre-fight action you could imagine.
