I guess you could purchase 100 guns from one store, or you could purchase one gun from 100 stores. I'm not sure that I can give you an answer there.
There's a lack of trust between the authorities and the firearms businesses, and there are bad apples in every barrel. There have certainly been some businesses that have been closed down, and rightly so. I'm not sure how we can improve that exchange of information. We do have some firearms collectors, skilled professionals, doctors, surgeons, engineers, oil field workers. They spend thousands of dollars every year on this. To put a dollar value on it, I don't think would help either.
