If more guns = more crime, then as the number of guns rises so too must crime. if crime goes down when the number of guns goes up then more guns = more crime must be false.
Violent crimes reported, as per the FBI:
Violent Crime - Crime in the United States 2008
Thus, the nuimber of crimes has gone down.
Not just the crime rate, but the raw number of crimes.
Now, according to the USDOJ, in 1994, 44 million Americans owned 192 million
firearms, 65 million of which were handguns.
The BATF notes that ther were 108,000,000 NICS checks for gun transfers, the majority of which were for new guns. Assume that only half this number were for new guns, and you get 54,000,000 new guns (1999-2009).
So, using just that low estimate and ingoring the 5 years not covered by the data, the number of guns in the US increased 28% 1994-2009.
Crime down 25%
Number of guns up >28%
More guns does not equal more crime.
