Have you ever seen an inanimate object get up, of its own volition and kill someone? It is the person who uses the object, and not the object itself that is to blame; it is merely a vehicle. Cain didn't kill his brother with a gun. Ever hear of Prohibition? People who want something that has been outlawed will find a way to get it. Enterprising people will find a way to supply the demand. A lot of people were murdered during the Prohibition era. Outlawing something doesn't guarantee its extinction.
