Why are DHS & FEMA on College Campuses?

On June 9, 2010 the Springfield-Greene County Office of Emergency Management issued a press release stating they would be “coordinating a hazardous materials and bomb response drill Thursday, June 10, beginning at 9 a.m. at Missouri State University.
During the drill, the Springfield Homeland Security Response Team… will respond to a simulated armed suspect entering a building with chemical weapons and a bomb.
The team will practice locating and apprehending the suspect, responding to casualties, removing hazardous materials and locating and safely removing the bomb.”

Why are did they choose a college campus? And why did they wait until virtually the last minute to inform local media? Is there an ulterior motive to indoctrinate young men & women into accepting the Police State?
