I don't know what the answer is. This event is extremely disturbing to me, especially since it seems that the goal was maximum damage to innocent people. The Olympic stadium bombings in Atlanta were similar but this is worse. I've had lots of traumas in my life and the only thing that seems to help me is the attitude that I don't want to let the bad guys win. Therefore, I refuse to live in fear because that will only contribute to my continued harm, which is the terrorist's goal.
