My service took me all over the world and taught me that regardless of the country cops all had one thing in common--they were Warriors.  Police officers held the "Thin Blue Line," that invisible, thread-like, intangible barrier that separates the bad from the good, the wolves from the sheep.  The police, no matter what government they serve, allow us to sleep peacefully in our beds at night.  And, while often times we criticize and disparage them, they are the first ones we call when we are in trouble.
