Hey....I didn’t see any data on the number of firearms purchased during that same period?
Need a chart correlating gun deaths and gun purchases, by state.
Here is the short version:
X
A shorter period of time so the number of purchases would be higher and NICS Checks for long guns can be for more than one firearm.
November 1009 to November 2012 NICS Applications 156,577,260 total.
Over 156 million has to be a sizable increase.
