After the United States Supreme Court ruled that the 4th Amendment right to keep and bear arms was an individual right, the United States government needed a new way to keep the people from possessing firearms and ammunition. Enter Operation Choke Point.
This is an initiative aimed at the federal banking regulators to prohibit banks from opening accounts, doing business or allowing firearms and ammunition dealers, legitimate businesses in this country, to do credit card transactions.
Much in the same way that the federal government used the IRS to target conservative political groups and deny them non-profit status, the government is maaking it impossible for citizens to purchase firearms. It’s not illegal to own firearms or ammunition, but you can’t buy them. Remember, gun control isn’t about guns, it’s about control.
