Just read Scalia's majority opinion. Overall, I like it. It was narrowly tailored, with extensive substance on just what the Second Amendment means, which makes me very, very hopeful.
I think you'll agree with me after reading what Breyer had to say in dissent:
Far more important are the unfortunate consequences that today’s decision is likely to spawn. Not least of these, as I have said, is the fact that the decision threatens to throw into doubt the constitutionality of gun laws throughout the United States.God willing.
