this should help serve as a wake-up call and in fact has already probably caused far more death and destruction than would actually result from a 'dirty bomb' - sometimes merely called a 'panic bomb' - set off in the middle of a CBD. The lessons of social cohesion and predatory sides of human nature are also showing .. luckily offset though by strong compassion and altruistic actions. There might be predators but there are also heaps of champions and good people out there
