New York Times story today describing an incident of a new kind of bombing.
They don't even need the bombs anymore. Someone just has to shout that there is a suicide bomber, and an even wose effect is achieved. Who needs nails or shards of glass when you can have a stampede.
If this was intentional, it was horrible. If it was unintentional, and someone really thought they saw a suicide bomber in the crowd, then it is a horrible example of how fear can kill us, nearly all by itself.
