And now the Supreme Court has overturned over 100 years of judicial precedent and stood the Second Amendment to the Constitution on its head. The 5-4 decision in District of Columbia v. Heller, written by Reagan appointee Justice Antonin Scalia, holds that the Second Amendment protects an individual right to possess firearms for self-defense purposes unconnected with service in a well regulated militia.

As Josh Horwitz, Executive Director of the Coalition to Stop Gun Violence, recently wrote: “By deliberately omitting what test the Court is using to decide that [the District’s handgun ban and trigger lock requirement] unreasonably burden this newly proclaimed individual right to possess firearms, the Court leaves legislators and lower courts adrift at a time when public health data clearly shows the harm associated with handguns far outweighs any benefit from their use for lawful self defense.”

The decision is a terrible one and complete misreads the Framer’s intent in drafting in the Second Amendment. It is relatively narrow in scope, however, and leaves many critical questions unanswered. More importantly, it does not prevent gun violence prevention organizations from actively pursuing a wide range of legislative initiatives to reduce gun violence.

The harm from guns outweights any benefit from their lawful use. Debatable, but let’s assume it’s true. Shall we then start applying cost-benefit analyses to other articles in the Bill of Rights? Quick, grab a pencil!

The case of Huzaifa Parhat suggests otherwise.

Desalinated seawater from Hawaii, meanwhile, is being sold as “concentrated water”—at $33.50 for a two-ounce bottle. Like any concentrated beverage, it is supposed to be diluted before drinking, except that in this case, that means adding water to . . . water.

Comes now this story that underscores the latter point:

In New York City, it often costs taxpayers $250,000 just to fire one incompetent teacher. Some teachers remain on the payroll even after being convicted of serious felonies, requiring districts to hold disciplinary hearings behind prison walls.

“Protecting jobs of adults without regard to how well their students perform almost certainly will lead to greater costs, stagnant academic achievement, and greater dysfunction of our public education system,” says tenure foe B. Jason Brooks of the Foundation for Education Reform & Accountability.
