No, you are incorrect. A knife can cause harm. A baseball bat can cause harm. A homemade bomb can cause harm. Hands can choke. Fists can punch. Feet can stomp. Many things can cause harm. Shall we ban baseball bats? The citizens of this country need more than the panacea of gun restrictions. Perhaps law abiding citizens need guns in order to defend themselves from the thugs and lawbreakers who have access to all the guns they need - without restriction or registration.
