We had better deal with this panic stampede issue, or we will surely face the tragic consequences of ignoring it. HOW A STADIUM OR SPORTS ARENA CAN BE TURNED INTO A MASS DEATH TRAP
In the case I fictionally describe the precipitating immediate cause of the panic is a sniper firing into the crowd, but it could just as easily be accomplished by setting off pepper spray or dumping a few gallons of ammonia and yelling "poison gas!"
We have seen two very terrible, very fatal and very real-to-life examples in the last week. Chicago and now RI.
I am afraid it will take worse for the stampede mentality to wear off. Our people and our society simply have no reference to such situations ... and very few parents and schools take the time to train and raise individuals who do.
As you point out in your novel, it certainly can and will be used against us.
