I served in the Submarine force for four wonderful cool: )years, and not one time did I see an instance of anyone doing anything of the sort. It isn't difficult to find cases like these, you are sifting through MILLIONS of people serving at any given time. A thousand of these cases spread out between millions of service men and women makes for a VERY small percentage, I'd guess a smaller percentage than in the general population. If you are a pessimest and are looking to see things as bad, that is what you will see.
