Hollow point bullets are illegal on the battlefield according to the Rules of Engagement. What are they planning? Some say it's just surplus ammo to be used for target practice-some say there are islamist cells in the US ready to commit terror-some say just in case there is a real economic melt down and riots.

...The DHS has signed off on an “indefinite delivery” from defense contractors ATK that will include, for some reason, nearly 500 million high-power ammunition for .40 caliber firearms. The department has yet to discuss why they are ordering such a massive bevy of bullets for an agency that has limited need domestically for doing harm, but they say they expect to continue receiving shipments from the manufacturer for the next five years, during which they plan to blow through enough ammunition to execute more people than there are in the entire United States.
“We are proud to extend our track record as the prime supplier of .40 caliber duty ammunition for DHS,” reads an official statement from Ron Johnson, ATK’s president of Security and Sporting, who adds that his group will also be giving up weaponry to the DHS subdivision of ICE, or Immigrations and Custom Enforcement.
