The opposite of more guns, less crime is fewer guns, more crime:
Since 1998, gun crime in Massachusetts has gotten worse, not better. In 2011, Massachusetts recorded 122 murders committed with firearms, the Globe reported this month — “a striking increase from the 65 in 1998.” Other crimes rose too. Between 1998 and 2011, robbery with firearms climbed 20.7 percent. Aggravated assaults jumped 26.7 percent.
