Such weapons may be part of the next wave in terrorism, national security analysts say. Fifteen thousand raucous hockey fans fill a downtown stadium on a Friday night to see the Washington Capitals take on the Philadelphia Flyers. But shortly after the 7 p.m. face-off, terrorists trigger an explosive charge that showers poisonous chemicals over the crowd. Washington, D.C. s proud new stadium becomes a hellhole of death and confusion.
People reel in all directions as crowds push their way to clogged exits.
Others fall to the ground choking and coughing. Their skin blisters. People attempting to help become victims themselves after breathing the poisoned air. In the aftermath of this hypothetical attack, surging crowds stampede over each other in panic. The city s 911 emergency lines flood with calls for help and medical assistance.
