Jon R. Lott, Jr. writes in the Wall Street Journal:

Yet despite being at the center of the gun-control debate for decades, neither President Obama nor Ms. Feinstein (the author of the 1994 legislation) seems to understand the leading research on the effects of the Federal Assault Weapons Ban. In addition, they continue to mislabel the weapons they seek to ban. …

Ms. Feinstein points to two studies by criminology professors Chris Koper and Jeff Roth for the National Institute of Justice to back up her contention that the ban reduced crime. [But these authors concluded just the opposite]. …

The large-capacity ammunition magazines used by some of these killers 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.  …

Ms. Feinstein’s new proposal also calls for gun registration, and the reasoning is straightforward: If a gun has been left at a crime scene and it was registered to the person who committed the crime, the registry will link the crime gun back to the criminal.

Nice logic, but in reality it hardly ever works that way. Guns are very rarely left behind at a crime scene. When they are, they’re usually stolen or unregistered. …

If we finally want to deal seriously with multiple-victim public shootings, it’s 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.
