This clerk may suffer from what Col. Jeff Cooper called "Hopophobia" (I think that's it) which supposedly describes someone who projects the fear they have of what they would do with firearms (bullets, etc.) on others. There is an article describing this condition in the current "American Rifleman." It helps me understand the unreasonable mind sets of many of the fiercest 2nd amendment opponents, check it out.
hoplophobia literally "fear of hoplites" from ancient Greece, a hoplite was primarily a free citizen who was usually individually responsible for procuring his armor and weapon...
Interesting. Thanks for that.
