What other countries and even cities in the USA have already learned, even before the Boston Marathon bombing, is you ban all backpacks in the areas where large amounts of people congregate like at the finishing line of a marathon! This is a simple solution for a potential huge problem.
So why wasn’t this simple security operation performed in Boston prior to the backpack bombing? The citizenry should be asking that question of their local leaders and politicians.
Moreover, the citizenry also needs to always be more vigilant because when security breaks down citizens have to be more aware of what goes on around them. Because Israel has had so many bombings in the past a common practice there is if anyone sees anyone leave anything on the ground and leave or if they see anyone get out of a car and mysteriously leave anywhere near large groups of people the citizens are known for immediately letting authorities know what just happened and they also try to get a good description of who committed the suspicious act. Consequently, you do not hear of many bombings in Israel any longer.
What is disturbing about the video shown of the two backpack bombers walking through the crowd at the finish line at the Boston marathon is about half of the people there, the techno-slaves, had their faces pointing downward fixated on their cell phones and could not have noticed anything unless it hit them on the head! It is sad to always see so many techno-slaves hunched over their cell phones most everywhere you go these days as the big beautiful world passes them by. Philosophers will tell you that techno-slavery chooses you. You do not choose techno-slavery.
