Larry Pratt, “Gun Grabbers Have No Proof Washington DC’s Gun Ban Laws Have Worked” In 1991 there was a study published in the New England Journal Of Medicine by four authors one of whom was at the time at the University of Maryland. The study, titled “Effects of Restrictive Licensing of Handguns on Homicide and Suicide in the District of Columbia,” purported to show the 1976 DC gun ban law decreased murders. But, this study has been exposed as a methodological mess and a fraud. In a review of this study, Dr. Edgar A. Suter, chairman of Doctors For Integrity In Research And Public Policy, notes the following:
The study’s claimed apparent, temporary and miniscule homicide drop occurred two years before the DC gun ban law took effect.
The study used raw numbers rather than population-corrected rates exaggerating the authors’ misinterpretations.
The study conveniently stopped as Washington DC’s overall homicide rate skyrocketed to eight times the national average and the :black, male, teen homicide rate skyrocketed to 22 times the national average.
