We are all lucky that these devices did not blow up and harm anyone. With the insufficient postage, it ensured that the package would wind up at either place that was designated. That is in fact fairly scary, especially given the routes that these packages would have travelled into and out of the city. When we get to a point where crazy people target anyone to cause fear, it is awful. There is no justification. I am surprised by the question of a group doing this to further their cause. To cause harm and strike terror in people is not a laughing matter for me. I find the divisiveness unsettling to say the least.
