It's not the gun that kills. It's the human person who lacks proper moral formation that kills. Will he likewise call us to set aside the other weapons used to kill people, like those that are used to commit suicide, deadly drugs, automobiles, and so many other ways to kill? I am writing a book right now about the protection of human life. In my research, I discovered that except for auto accidents, adolescent suicide causes the deaths of more youth than all other causes, including gun violence.
