Here’s my answer to a Doctor or Nurse who asks me if I have any firearms in my home:
“I don’t discuss my personal or family security measures with anybody but members of my family.”
““I don’t discuss my personal or family security measures with anybody but members of my family.””
Your answer is then in the books. And bit-by-bit they build up their database, knowing that evasive answers are just the same as a direct “yes” answer.
