I guess looking out for the folks doesn't include gun owners or 2nd Amendment supporters. O'Reilly is a blowhard who is completely out of touch with the 21st Century and most Americans. There is no danger of O'Reilly reading this post. He doesn't personally use the Internet or social media. His information is filtered by aids and he has a very narrow view that mostly aligns with he crap put out by the mainstream media.
I won't even dignify the horrible, and likely unconstitutional, idea of a National Gun Registry with a counter argument. As for the idea of federalizing gun crimes, when has putting the Federal Government in charge of anything ever made it better?
