To be clear:
The problem is that the plaintiff does not provide a reasonable remedy.
If Colorado offers a concealed-cary permit to someone who is not a resident of Colorado, than anyone from a state which has reciprocal recognition of licenses can seek a license in Colorado to get around their own state’s licensing. Presumably, their own state has more information on which to decide if the permit should be issued.
If the court forces a state to have reciprocal licensing of all other states, then if any state DOES issue out-of-state licenses, the least regulated state essentially licenses all other states.
The only real option that court had to allow the plaintiff to get a concealed-carry permit would be to decide in favor of a universal right to concealed carry, which is not consistent with the common law on which the 2nd amendment was based.
Aside from the fact that any permit requirement in itself is an unconstitutional infringement, anyone who does not qualify for that permit should be incarcerated or closely monitored.
