In a puzzling, unexplained development, the Obama administration has been buying and storing vast amounts of ammunition in recent months, with the Department of Homeland Security just placing another order for an additional 21.6 million rounds.
According to one estimate, just since last spring DHS has stockpiled more than 1.6 billion bullets, mainly .40 caliber and 9mm. That's sufficient firepower to shoot every American about five times. Including illegal immigrants.
