"We are disinclined to engage in another round of historical analysis to determine whether eighteenth-century America understood the Second Amendment to include a right to bear guns outside the home," Judge Richard Posner wrote in the court's majority opinion.
"The Supreme Court has decided that the amendment confers a right to bear arms for self-defense, which is as important outside the home as inside. The theoretical and empirical evidence (which overall is inconclusive) is consistent with concluding that a right to carry firearms in public may promote self-defense," he continued.
"Illinois had to provide us with more than merely a rational basis for believing that its uniquely sweeping ban is justified by an increase in public safety. It has failed to meet this burden," Posner wrote.
