From the Dave Kopel at the Volokh Report, Law Enforcement Trainers File Scotus Amicus Brief against Maryland Rifle Ban

Citizens should be able to choose the same high-quality defensive arms that peace officers choose
 
Last week the International Law Enforcement Educators & Trainers Association filed an amicus brief in a U.S. Supreme Court case challenging Maryland's ban on many common semiautomatic rifles. The case is Bianchi v. Brown, and it has an unusual procedural posture; it is a petition for certiorari before judgement. Yet the case is one on which the U.S. Supreme Court has already ruled.

This post will first summarize the amicus brief, and then provide the procedural background, which is detailed in the Bianchi plaintiffs' cert. petition.

The facts about the banned rifles

As detailed in the amicus brief, the semiautomatic rifles banned by the Maryland General Assembly fire only one shot each time the trigger is pressed. This is the same rate of fire as the most common semiautomatic handguns, such as those made by Glock, Smith & Wesson, or Ruger.

The claim by gun prohibition advocates that such guns fire 300 to 500 times per minute has no basis in fact, and is contrary to common sense. It would take a superhuman trigger finger pull a trigger at the rate of 5 to 8 times per second, let alone do so for a full minute.

Nor are the banned rifles, including those based on the AR-15 platform, more powerful than nonbanned rifles. To the contrary, their standard ammunition is .223 inch or 5.56mm bullets that are small compared to most other rifle ammunition. Accordingly, their kinetic energy is lower.

Because the banned rifles are more powerful than handguns, but less powerful than most other rifles, the relatively low wounding power of this ammunition has been confirmed by decades of study by the US Army's Ballistic Research Laboratory.

Moreover, as documented in police training manuals, the banned rifles are the safest for defensive use within buildings, because their ammunition is especially unlikely to penetrate a wall.

Since when do actual facts have anything to do with gun control?
