How to stop invaders from buying guns

The invaders are all receiving drivers licenses. They are all receiving prepaid credit cards connected to the United Nations. They are all being let in by your government. Some of them are foreign military and foreign special forces. With the drivers license they are given, and the money they are provided, they are buying guns in American gun stores. They are all given a smart phone so that they can receive orders from their superior officers. They are forming sleeper cells and they are preparing to destroy America as bad or worse than what happened to Israel by Hamas on October 7, 2023. Therefore, if you are somebody who sells guns, you should be putting up a sign that says “we reserve the right to refuse service, and require additional proof of identity and residency.” And then you should require them to give a bill, or some sort of other extremely personal document from 10 years ago or more, the older, the better, to prove their identity. Something like a utilities bill or something from their bank or something of that nature. 10 years old or more.
