Citation needed, given that it flies in the face of the vast majority of research into the effect....
ok from your own links.
An article by Moody and Marvel uses a more extensive data set and projects effects beyond a five-year span. Though their data set renders an apparent reduction in the cost of crime, Donohue and Ayres point out that the cost of crime increased in 23 of the 24 jurisdictions under scrutiny. Florida was the only jurisdiction showing positive effects from Shall-Issue Laws.
The National Research Council, the working arm of the National Academy of Sciences, claims to have found "no credible evidence" either supporting or disproving Lott's thesis

So you support a claim of "vast majority of research" with a book written by an economist?
I'll concede that it may not lead to an increase in the violence of the crime.
And side with the "it doesn't really make any difference" National Academy of Sciences.
Also why is it countries with very lax gun laws always seem to have more issues with the illegal ones?
