 When that terrorist bomb ripped apart the federal office building in Oklahoma City on an infamous April 19th years ago, Mark was on the scene within 10 minutes. Now today, that scene of horrendous carnage and violence is a tranquil memorial site in downtown Oklahoma City. One night when I was speaking in that city, Mark, who was a police officer, took me there for a personal tour that was pretty moving. Gesturing toward that quiet memorial area that stands where the building once stood, he showed me where the nursery had been.
