With all due respect, Al, I disagree. Under a QI analysis, the officers will not be expected to make an assessment of the constitutionality of the new laws, or of the interaction between Heller and the new laws. Statutes are presumed constitutional, and LEO trying to enforce the new laws will likely be entitled to QI for operating on that presumption.
