I found a New York Times article, How They Got Thier Guns, that breaks down what guns were used in mass murders and how they were obtained. It seems that just about all of these shooters passed background checks, just about all of the shooters had more than one firearm, and many were able to kill just as many people with a shotgun or handgun; however, within minutes of these shootings happening, antis are out campaigning for universal background checks, 10 round magazine limits, and a ban on assault weapons when none of these laws would have stopped these killers.
The only common denominators per the article is that the killings happened in gun free zones and the killers all showed signs of mental illness well before they went on their killing spree. It's just odds to me that regardless of facts and logic, the antics have been able to convince a large portion of Americans that lax gun control, e.g., assault weapons, high capacity magazines, and gun show loopholes, are to blame for the continued carnage.
