Emergency-services professionals know that one of their key tasks is to take care of the people who deal firsthand with crises and trauma: firefighters who run into burning buildings, first responders at the scene of a mass murder, personnel who try to rescue people from floods and tornadoes. These brave people do truly heroic work under the most trying conditions. Sadly, they often suffer from post traumatic stress syndrome (PTSD). Consider:
• On April 16, 2007, a student at Virginia Tech killed 32 people and wounded 17 others. It was the deadliest shooting incident by a single gunman in our country's history. Police got inside the classroom building in eight minutes and found the shooter dead. But the suffering had only just begun. As medical personnel carried the dead students out of the building, cellphones on the students' bodies began to ring. Horrified parents were calling to see if their children were safe. Some of the first responders had great difficulty getting over the scene. At least one of them retired early from a career he loved.
