http://www.msnbc.msn.com/id/19853442/ "The study did not examine how many of the police officers killed this year were shot with weapons that were legalized three years ago, but . . ." But?

Better to just assert it with confidence and then attack in ad hominem fashion anybody who questions your conclusions by smearing them as an obvious anti-LEO type.
