Why is DHS stockpiling over 1.3 Billions rounds of ammo?

WHAT POSSIBLE USE COULD THE DEPARTMENT OF HOMELAND SECURITY HAVE FOR 1.3 BILLION ROUNDS OF AMMO.  ARE THEY EXPECTING A CIVILIAN UPRISING OR MAYBE JUST PLANNING SOME MASSIVE ATTACK ON THOSE IN THIS COUNTRY WHO WILL NOT BUCKLE UNDER TO THE PLANS OF THE OBAMA ADMINISTRATION. 

ONE THING FOR SURE, IF DHS DOESN'T USE THIS AMMO IT WILL STILL BE THERE WHEN THE NEXT ADMINISTRATION TAKES OFFICE---PERHAPS ONE THAT DOES NOT FOLLOW THE  POLICES OF BARACK OBAMA.
