And here is Dr. John Lott on this study….
Problems with a new study from Journal of Criminology claiming that permitted concealed handguns have no effect on violent crime - Crime Prevention Research Center
As past surveys of the literature have shown, there have been other studies that have found that right-to-carry laws don’t reduce violent crime, though they have been in the distinct minority. Yet, the worst that they can say is that these laws don’t produce a bad effect.
No explanation is offered for why these authors pick the states or years that they examine? This is important because the test that they are preforming compares these states relative to one another during the period that they all have right-to-carry concealed handgun laws. When authors throw out data there had better be a good explanation for why they are doing it, but no explanation is offered here.
These guys seem completely unfamiliar with my findings in the 2nd and 3rd edition of MGLC. That is important because those editions spent significant time going through and talking about what determined the number of permits issued and the impact of the number of permits on the crime rate.
Permit issuance rate depends crucially on the cost of getting a permit (fees, training period, how long the laws have been in effect, also where you can use the permit). This is important in differentiating the supply and demand issues for number of permits issued. For example, during the period studied the cost of a Texas permit was $140 and a training period of 10 hours while in Pennsylvania was $19 and no training.
No explanation is offered for why these costs of getting permits, which differ significantly across these states, are completely ignored.
Despite these problems, it would have been interesting to see the results without including the number of Federally Licensed Firearm dealers, a number that is likely very correlated with the number of permits.
They also have no or virtually no data on permit issuance prior to right-to-carry law being adopted. Strangely permit issuance is as a percent of the total population, not the percent of the adult population, thus adding randomness into the relationship.
No explanation was ever offered by Lott why his study concluded that murder, assault and car theft rates were more closely tied to the population of black women over 65.....than teen aged black males.
A conclusion which is clearly nonsense.
What, was granny jacking cars and popping caps off in people's asses? If you're a Lott supporter....apparently.
Nor could Lott explain why 7 of 10 of the most violent states in the country had higher than average gun ownership rates, while only 2 of 10 had lower than average gun ownership rates.
Nor could Lott explain why ALL of the top 10 states for gun deaths were among the top 20 for gun ownership rates.
Nor could Lott explain how his process produced the utter nonsense results that the more rural and less populated an area...the higher the crime rates. A conclusion refuted by the FBI every year.
Nor could you explain why Lott created the fake online personality 'Mary Roch' to support his theories, praise his books, and laud his genius.
Remember, when you cite Lott.....you've gotta take all the batshit that comes with it.
