A key comment on the ruling was provided by Alan Gura, a well-known gun rights activist. He said: "The idea that the city can prohibit absolutely the exercise of a constitutional right for all people at all times,that was struck down" [emphasis added]. I see that as in line with Scalia's previous rulings (in DC and Chicago) that flat-out banned handgun ownership by anyone. But, he emphasized while individual gun ownership is a Constitutional right, the various government entities are not enjoined from passing regulations on gun ownership and use as long as they don't flat-out prohibit gun ownership by law-abiding citizens.
DC and Chicago had the highest per capita rates of gun crimes while the absolute bans were in effect. They probably still due.
