Whenever a question arises about personal responsibility, I ask myself "Who am I? The answer comes easily in each circumstance: I'm a father, husband, brother, colleague, responsible citizen, fellow gunner in a gunshop, etc. The obligation is clear. A shop that always dealt fairly with you should not be displeased with a customer advising another about a gun, one way or the other.

A gunshop is a clearing house of merchandise. The people in the aisles are customers like you. Dealers may be more or less knowledgeable than some customers about their guns. If a common call of caring is subordinate to future callings in the shop, you get what you got, Jimmy: an itch worse than a missed shot.
