What the Hell does That mean?
Weasel words to infringe?
It is a little vague - I interpret it as referring to a decision in favor of individual rights in the matter that still leaves a loophole for whatever legislation Congress cares to propose. Having one's cake and eating it too, in essence.
The real difficulty is what happens to the considerable body of existing law should its underlying premise be stricken down. For example, does a gun store operator still have to keep his paperwork in this case? What if he doesn't? And who will decide?
Even under the best of circumstances, a ringing endorsement of the Second as a fundamental individual right, the fight will not be over. We're in this for the long run.
It means that even if the 2A is confirmed as an individual right, the individual states have the right to impose infringement as they see fit.
