A Moron I Encoutered

Once upon a time ago I purchased a coffee cup at a gun show with this image:

I took it to my place of work, at the time I was the security officer on the night shift at the former Midway Hospital in Saint Paul and it was converted into an office building for the Health East Care System.  Apparently someone saw the coffee cup with the image on it and felt threatened by it.  Can you believe that?  The site supervisor for the security department had to ask me to remove the cup from the site.  And we let these morons vote?
