You are the  southwest regional homeland security director. You are preparing  a scenario for  your district to test its effectiveness in response to a  chemical attack. You  want your chemical and hazardous response team to consider  this a live exercise.  You are planning targets such as major political and  sporting events that are  scheduled to take place in open stadiums in Phoenix,  Arizona; San Diego,  California; Santa Fe, New Mexico; and El Paso, Texas.  Considering a radical  terrorist cell, what would be their chemical of choice  and how would they  disburse the chemical to ensure maximum effective coverage?  What infrastructure  defenses do you believe they need to overcome and what  contingencies need to be  looked at to ensure all areas are covered?
