From Bearing Arms:

U.S. District Judge John L. Kane, an 86-year-old appointee of Jimmy Carter back in 1977, made the eyebrow-raising decision in a case known as Rocky Mountain Gun Owners v. Polis, which challenges Colorado’s newly-enacted three-day waiting period on all gun sales. Kane denied the group’s request for an injunction that would have halted enforcement of the waiting period while the litigation continues, ruling the plain text of the Second Amendment only covers the right to keep and bear a firearm, not to purchase or acquire one for lawful purposes.
