It has to do with laws concerning domestic violence. Theres all sorts of forms and paperwoork that needs done when a patients checks into a hoospital. Some docs ask as part of their protocols, some insurance companies ask, etc... They ask questions to all patients about if they feel threatened, do they live alone, are they afraid to go back home, does anybody want to hurt them and so on, the gun question is included as part of the law passed. Not sure if its part of a grand plan, I'm sure folks who want could glean info off it, but as always deny, deny,deny.
