This week in the studio I welcome a man who spent over 23 years in the United States military. He is a for former enlisted and an Airborne Ranger Infantry Officer. My guest has spent a lifetime studying the Science of Killing and Combat, which led him to being an expert witness and a consultant in State and Federal courts. He has testified before the US Senate and Congress and has even been cited in an address by the President of the United States. His books are legendary in the military, law enforcement, and first responder world, and he is here tonight to explain the truth about Lethal Combat, violent visual imagery, Terrorism, and PTS. Please welcome Lt. Col Dave Grossman…..
