Alan Colmes forces Giuliani to say Whether He thinks that the Brady Act Reduced Violent Crime

If there is an academic study by Economists or Criminologiist that finds tht the Brady Act reduced violent crime, I hope that someone will please point to it for me. Alan Colmes deserves some respect for forcing Giuliani to answer this question.

COLMES: But the Brady Bill did lead to a decline in crime. You have to acknowledge that.
GIULIANI: The Brady Bill was part of the crime bill. The crime bill overall helped. I am not saying it did not help. But the reality is that what we did in New York was nothing short of totally unexpected. Nobody thought it was possible.
