‘Military-Style Weapons’ - John R. Lott Jr. - National Review Online

The police in Aurora, Colo., reported that the killer used a Smith & Wesson M&P 15. This weapon bears a cosmetic resemblance to the M-16, which has been used by the U.S. military since the Vietnam War. The call has frequently been made that there is "no reason" for such "military-style weapons" to be available to civilians.
Yes, the M&P 15 and the AK-47 are "military-style weapons." But the key word is "style" — they are similar to military guns in their aesthetics, not in the way they actually operate. The guns covered by the federal assault-weapons ban (which was enacted in 1994 and expired ten year later) were not the fully automatic machine guns used by the military but semi-automatic versions of those guns.
The civilian version of the AK-47 uses essentially the same sorts of bullets as deer-hunting rifles, fires at the same rapidity (one bullet per pull of the trigger), and does the same damage. The M&P 15 is similar, though it fires a much smaller bullet — .223 inches in diameter, as opposed to the .30-inch rounds used by the AK-47.
The Aurora killer's large-capacity ammunition magazines are also misunderstood. The common perception that so-called "assault weapons" can hold larger magazines than hunting rifles is simply wrong. Any gun that can hold a magazine can hold one of any size. That is true for handguns as well as rifles. A magazine, which is basically a metal box with a spring, is also trivially easy to make and virtually impossible to stop criminals from obtaining.

If we finally want to deal seriously with multiple-victim public shootings, it is about time that we acknowledge a common feature of these attacks: With just a single exception, the attack in Tucson last year, every public shooting in the U.S. in which more than three people have been killed since at least 1950 has occurred in a place where citizens are not allowed to carry their own firearms. The Cinemark movie theater in Aurora, like others run by the chain around the country, displayed warning signs that it was prohibited to carry guns into the theater.
