Congress could also intervene. This law is designed to nullify the right to carry arms in public that Bruen recognized. I think Congress would be well within its powers to regulate public carry in Hawaii (and California, Maryland, and New York) under § 5 of the 14th Amendment. 3/3

The plaintiffs have a reasonable chance at Supreme Court review. A clear circuit split exists on this issue. Hawaii's law effectively bans public carry throughout the state. Hawaii's law is also pretextual and serves no legitimate governmental interest. 2/3

Also note that, contrary to the Warren-Blumenthal letter, the Constitution vests state legislatures, not governors, with primary authority to request federal assistance.

But the federal government can defend federal law without relying on state law enforcement. See 10 U.S.C. § 252. Making federal enforcement subservient to state governments undermines the paramount authority of federal law. Imagine if that had been the policy during Jim Crow. 2/3
