In the Pilot and across the media, we are hearing the calls again to “do something ” about mass shootings, and Len has pointed out that ese shootings have a far greater effect on our lives than the number of victims would indicate. So, let’s do what the number show us would do the most good, within the limits of the Constitution and reality.
John Lott, statistics on mass shootings
First, most of these mass shootings are accomplished with ordinary handguns. Not ARs. And most of those in which ARs were used, could have been just as deadly with those handguns(with the exception of the Vegas shooting) So, AR bans are not the solution.
But there is one change in the law that exceeds all other possibilities that the Constitution allows to mitigate mass shootings.
Lott finds that 34% of mass shootings are ended by armed citizens. This differs from FBI statistics because of some rather odd classification methods. For example, if a shooter is driven away or forced to shelter by an armed citizen, and later arrested by police, the FBI does not count that as stopped by the citizen. Lotts classification methods are explained in the link. As year by year the number of people carrying concealed has increased, so has the number of shootings stopped.
But the overwhelming difference is that when properly categorized, the overall share of shooting stopped was 34%, but in areas where citizens can be legally armed, the percentage stopped by citizens rose to 59%.
So, the number one thing we can do to reduce the number of people killed in mass shootings is to eliminate gun-free zones.
