From the October 23 edition of CBS' CBS Evening News with Scott Pelley:
LARRY PRATT: I'm Larry Pratt, executive director of Gun Owners of America where we have advocated -- really ever since Columbine -- that the problem of mass murder in this country is the gun-free zone. We have a federal law that says that schools must be gun-free zones unless a state goes through an enormous amount of trouble. All but two of the mass murders in our country have occurred in gun-free zones. Even while our violent crime rate has been going down, more Americans are owning guns, but not in gun-free zones.
