FTA:
But U.S. District Judge Janet Bond Arterton in New Haven in a 74-page ruling rejected those claims, saying the group failed to establish that assault weapons and large capacity magazines are commonly bought and used for self-defense.
Arterton, an appointee of former Democratic President Bill Clinton, cited “persuasive” evidence by the state that assault weapons are instead more often sought out for their militaristic characteristics and are often used in crimes and mass shootings.
This is an interesting interpretation on the Second Amendment that will probably end up being brought before the Supreme Court. Unfortunately, with the current roster of Supremes I expect it to fail.
Lightweight, high-velocity rounds like the 5.56 tend to present less of an overpenetration risk than heavier, slower ones like the 9mm or 45ACP, even hollowpoints. Things like birdshot or Glasser frangible ammo can’t be counted on to reliably stop a threat so those aren’t a great solution either. Overpenetration is a serious concern with any firearm that is viable for self-defense, there’s no getting around it. Any time you pull the trigger you run the risk of killing an innocent person downrange of your intended target.
