My heart felt sympathy to all Americans and in particular those who have suffered. Did anyone think why this has happened and what would have prevented it? We continue throughout the world to create zones of safety for criminals, idiots, madmen and terrorists to operate in without fear and free from any form of viable defense. Having the only option of standing meekly by and watching. We then wonder why crime increases and horrific incidents take place in the so-called safety zones. Perhaps the people and organisations that advocate these safety zones and measures are the real terrorists. Any bets they now ban knives on planes, that should fix it by creating a more safe zone.
