The ACLU considers the decision in New York State Rifle & Pistol Association Inc. v. Bruen to be a loss for civil liberties:
The Supreme Court struck down New York’s restriction on concealed carry and eroded the legal basis for gun regulations, ruling that states can regulate guns today only if they can point to similar laws in the 18th and 19th centuries — even though the threat of gun violence today differs markedly from those eras. Justices Kavanaugh and Roberts made clear, however, that in their view, states could impose various prerequisites before granting a public carry permit, including background checks and training requirements, as long as they restrain licensing officials’ discretion. The New York Civil Liberties Union and the ACLU submitted an amicus brief in the case, arguing that the unregulated carrying of weapons in public undermines the sense of safety required for an open, healthy democracy, and that state and local governments have long imposed strict regulations on the public carrying of guns.
This isn’t surprise as they long ago gave up any interest in protecting civil liberties, having drifted way too far leftward. They used to stand up for things they did not agree with, no matter how odorous, in defense of the individual. Now they are at the point where they refuse to stand up for a specifically enumerated right.
