My oldest son was volunteering at the finish line. He was directly across the street from the first blast. He wasn't injured except for ringing ears. Luckily he was instructed to move people out of the area so he didn't see the badly injured and dead people. What is this world coming to? Two weeks ago my younger son's college was locked down due to a possible gunman. It turned out to be unfounded but it was a scary few hours. You think your children are safe at school and work and because of crazy sick people in this world, no one is safe anywhere. I have had two scares in two weeks, but my boys are safe...my heart breaks for those who lost loved ones today and those who were injured. I hope they find the person or people responsible for this and throw the book at them.
