A dilemma arises. Do you contain all the people at the football game and begin testing them for possible biochemical exposure with delayed effects as in biological warfare or do you disperse the obvious massing of people from a potential attack which hasn't yet culminated or do you treat it as an isolated event,..nothing to see here, move along? Probably wouldn't hurt to disperse and voluntary quanrantine for several days and catch up on homework.
Holy .... you're right.
A dilema it is.
