For more than half-a-century, Uncle Sam has been giving banks the legal tools to snoop into the otherwise-private affairs of their customers. Now, they are monitoring the exercise of their Second Amendment rights.

Thanks to a recent move by the International Organization for Standardization (ISO, headquartered in Switzerland), U.S. banks are starting to build databases on their customers’ purchases of firearms and ammunition. And, of course, they are ready and quite willing to share that information with federal law enforcement in the name of providing a public service to identify “mass shooters.”
