Piers Bullies, Silences Gun Advocate; Calls Him Liar MORGAN: Now, you can see, this is an astonishing picture. This is a car outside Sandy Hook school. That is a bullet hole from a ricochet bullet fired from inside the school. Look at the power. Look at the impact. Imagine what that was doing to a little child of 6 or 7. Now, John Lott, your answer is more guns makes America safe, even though you look at the statistics, you have 300 million in circulation and you have the worst gun murder rate of any of the wealthy countries of the world by a massive multiple. How do you justify the claim more guns makes more safe people in America? I don't -- don't get it. JOHN R. LOTT, JR., AUTHOR, "MORE GUNS, LESS CRIME": Every place that guns have been banned, murder rates have gone up. You cannot point to one place, whether it's Chicago or whether it's D.C. or whether it's been England of whether it's been Jamaica or Ireland... (CROSSTALK) MORGAN: That's a complete lie. LOTT: It is not! MORGAN: It's a complete lie!
