In the matter of DC v Heller.
It could have been worse but , all in all, I’m pretty happy. Obviously, the gunloons get a debating point–they can now say the Constitution protects an individual right to firearms. DC is a big loser; in addition to having to pay taxes and sending its citizens to the armed services and not having representation in Congress–they also have a court of political hacks telling them that what an overwhelming majority of their citizens want doesn’t matter.
OTOH, Fat Tony Scalia and his cronies have said licensing, registration, and other forms of regulation pass Constitutional muster. Assault weapons and other “dangerous” firearms can be banned. Bans against concealed weapons, carrying weapons in schools and government buildings (Et Tu, Nino?) and other locations are kosher.
The gunloons also lost a debating point: that the 2A serves as a protection against tyranny. Uh, uh sez Fat Tony; the 2A is about self-defense–at home.
