These weapons have no purpose other than to kill people. Do you think you can walk into Cabellas and buy the lethal injection cocktail? Is it reasonable to go to a department store and buy unlimited quantities of potassium cyanide? Should it not be as alarming to watch someone walk down the street with an AK- rifle as it is alarming to watch someone walk down the street with a giant knife? Buying weapons of murder should be a highly regulated and rare occurrence.
