Why......?

A soldier opened fire at a U.S. Army base in Fort Hood, TX on Thursday, unleashing a stream of gunfire that left 12 people dead and 31 wounded. Authorities killed the gunman, and apprehended two other soldiers suspected in what appears to be the worst mass shooting at a U.S. military base.

The shooting began around 1:30 p.m., Lt. Gen. Bob Cone said at a news conference. He said all the casualties took place at the base's Soldier Readiness Center, where soldiers who are about to be deployed or who are returning undergo medical screening.
