This is a boundary violation - the docs are not licensed by the states as safety experts, so if any harm comes to you because of their advice on the matter (i.e. "lock up the guns" - and you can't get it out in time to resist a thief/rapist/etc.), then their malpractice insurance won't cover it.

Docs need to be reminded of this constantly. Also, getting up and walking out when you're asked that question will have an effect.
