I don't really care, but it's a ripoff to have to pay extra for a background check for each gun. If someone wants a gun to commit a crime, why would they have to use the one they're buying now when they already have other guns?
And, criminals don't buy guns legally because they have criminal records & won't pass a background check. And they don't want to leave all their information, which police get copies of. That's why registration & restrictions are useless. In fact, it's a crime for a criminal to even walk into a gun shop or even attempt to purchase a firearm or ammunition or possess a single bullet.
