Justice Department's "Chokepoint" on Gun Ownership

According to the Washington Times, the Obama Administration has developed a new technique to inhibit private citizens from gun ownership, contrary to the Second Amendment to the Constitution.
In 2011,The Federal Deposit Insurance Corp. (FDIC) listed gun dealers at “high-risk” for loans. The basis for such decision is unknown, but we can speculate that it may have come from the Obama Administration.
As a recent follow-up, Eric Holder's Justice Department, which works for Obama, has developed a new initiative called Choke Point to open wide-ranging investigations of banks and payment processors associated with the businesses on the FDIC list. As of last year, Justice had issued more than 50 subpoenas to banks and payment processors. The banks have gotten this high-pressure message and rather than risk the complexities of investigation, they have significantly cut credit availability to gun dealers. This obviously reduces availability of guns to the public, as dealers are denied financing for expansion and the proper carrying of inventory.
An interesting aspect of the situation is that justice/Obama can do this, because the wording of the Second Amendment is that "Congress should make no law, etc." Apparently, the founding fathers did not anticipate the deviousness of future Administrations.
However, Congress can move to bring the situation into its proper perspective, in that it has constitutional authority to pass a law, which prohibits the Administration from these devious maneuvers, particularly with respect to public gun ownership.
