I wonder how many people look around and notice all the weapons at hand, not including the obvious like firearms, knives, etc? I am always amused when at a sporting event or the airport when security checks are being done that some of the most common items can be used as a weapon. I am a true believer that neccessity is the mother of all inventions and Darwin's Survival of the Fittest and when combined it can make a good combo.

Just a thought.
