From the October 12 edition of Fox News' The O'Reilly Factor:
BILL O'REILLY (HOST): Carson and I, we think alike in a lot of different ways. When you mentioned that you would have rushed the gunman, I said “yeah, didn't they do that on 9/11 in the plane that crashed in Pennsylvania?” Yes they did.
BEN CARSON: Exactly.
O'REILLY: When you mentioned that, the Nazis seized guns, one of their first policies were to get guns off the street. That's exactly true. The Warsaw ghetto showed that Jews in Warsaw who were armed could hold off the Nazis and if everybody had that then the Nazis would have had a lot more trouble doing what they did. So there is a lot of things that you say that I understand.
