"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. 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. 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." . . .
"A gun is a potential danger to more people if carried in public than just kept in the home. But the other side of this coin is that knowing that many law-abiding citizens are walking the streets armed may make criminals timid." . . .Judge Posner has given Illinois lawmakers six months to rewrite a state law that complies with the Second Amendment. "We went to court," said Todd Vandermyde, an NRA lobbyist. "We won. … Illinois will have a carry law by the Fourth of July. And if the mayor or the governor or anybody else doesn't like it, well, that's just too bad."
