I was having coffee with a former police officer (former Army MP, after leaving the military and becoming a police officer, served as a gang homicide detective and also was on the SWAT team) one morning, and during the conversation I asked him “Based on your experiences as a police officer, what lessons have you learned about real violence that you would be willing to share?” The very first thing he said was “real evil does exist in this world.” On this anniversary of 9/11, we would all do well to heed those words and remain ever vigilant, and be prepared to take a stand against the evil in this world.
