While returning from a class one day this past week, and munching a green apple, I was stopped by a complete stranger and asked for my backpack. Since he happened to have a 9mm Glock, a badge, and a digital camo uniform I did not argue. The rules say I can be stopped at any time and have to submit to a searched as part of my job. My backpack was thoroughly searched for anything on the prohibited items list. Just one of the many freedoms me and my co-workers give up to help keep the U.S. safe.
