I was watching an episode of my favorite television series LAW AND ORDER (SVU) one evening and it took my mind to a million places. The episode was about a mentally unstable man who decided to start killing cops. Some police officers watched their partners get shot in the head right in front of their eyes and couldn't do anything about it. They couldn't even find the shooter, which made some of them decide to quit. According to one of them "I would rather be a coward on the beach in Florida than become a dead cop".
The part that really struck me was the speech given to the officers in their precinct by their lieutenant, telling them that even though many people hate cops, and want them dead, they should never forget that their job is to protect and serve these same people. The speech ended with "please try and come back alive".
