Let's look at it another way. The reason for the POW flag is to remember "You are not forgotten" is the slogan. In the tower there is a man with a gun. It's a prison camp, barb wire, etc. The use of a bullet kit, real or simulated, accents the remembrance of why the flag was created in the first place. You should remember that a gun was to your head, or if not you the POW, then others are reminded of the inhumanity of being a POW. It's a pretty powerful statement and gives us as Americans a lot to think about when it comes to war in general.
