- Good start - lie in the title. It isn't restrictive licensing; it is
- a ban with a grandfather provision.
-
- >Whether restricting access to handguns will reduce firearm-related homicides
- >and suicides is currently a matter of intense debate. In 1976 the District
- >of Columbia adopted a law that banned the purchase, sale, transfer or
- >possession of handguns by civilians. We evaluated the effect of implementing

-
- Actually, they didn't.
-
- >The number of suicides and homicides was calculated for each month
- >during the study period, and the differences between the mean monthly
- >totals before and after the law went into effect were estimated.
-
- Note that they ignored population changes; including them almost
- completely accounts for the observed difference. (The interval used
- also excludes a rather extreme post-law murder increase.) Moreover,
- the data set doesn't differentiate between justifiable homicide and
- murder. There is a social benefit to reducing the latter; it appears
- that the population-adjusted difference observed is due entirely
- to the former.
-
- Moreover, the trend BEFORE the law was a decrease in
- population-adjusted murder rates, yet the model used assumes that it
- was constant. Comparing the average of a declining series with that
- of a mildly increasing average that starts at the end point of the
- decline is dishonest at best.
-
- >or suicides committed by other means, nor were there similar
- >reductions in the adjacent metropolitan areas in Maryland and
- >Virginia.
-
- Actually, on a population-adjusted basis, there were. Note that other
- jurisdictions that are comparable (Virginia and Maryland aren't) to DC
- did better in the post-law period than DC did, and they didn't have
- the law. So much for the effects of the law....
