It seems to be a "Tale of Two Days". Yesterday it was jubilation on the part of many that London had been granted the 2012 Olympics. Today it is one of sadness and anger with the terrorist attacks in the subway and on a bus. What can a person say? What can a person do? What can the government do? The people that perpetrate such horrors are madmen but they move in and out without being seen. How is one to locate and identify such people? How is one to protect its citizens without just locking down everything and bringing commerce and everything else to a halt? In WWII we knew who the enemy was, what he looked like, and where he was and could take appropriate action. In this war the enemy is invisible until it is too late. This enemy plays on fears but as one person long ago was quoted as saying, "The only thing we have to fear is fear itself". Still, how long will this go on and how do we defeat it?
