I'll save you a few pages of twisting in the wind. It doesn't. As it stands the government has no provision for federal registration except for Class III stuff. So what would be the purpose for registering guns that are already out there? And why would we tie this registration to medical records? Do you think it's out of convenience, or do you think that certain medical situations may lead to confiscation? Something like treatment for depression? And do you honestly think these cases will be ruled on a case by case basis or do you think it might be something broader than that?\
For instance, I have had marriage counselling. Does that simply mean a check mark in the "has received psychological treatment" box which might preclude gun ownership?
Now consider how many people who own guns who might not seek advice based on this. Do you want people refusing counselling because they are afraid of having thousands of dollars of equipment confiscated? Because you know there will be no offset for the expenses. It's about time we got honest about this, don't you think?
