John Popp catches up with World War II Veteran Peter Marshall Kniskern at the NRA Veteran's Shoot at the NRA Range last Wednesday. Kniskern was one of the youngest WWII veterans. He first volunteered when he was 13 years old, and he served between 1939-1946 in the Army Air Corps where he saw action in North Africa. He tells Popp that while times have changed, Americans must remember that there are some rights, like the Second Amendment, that are worth fighting for. Originally aired 11/11/10.
