No, that's still a problem. That's state law. Wherever federal law has been incorporated into state law, the SAPA will effectively be nullified regarding that federal law.
If we want duplication of federal law removed from Missouri law, we're going to have to lobby our state legislature to get it done.
Imo, the first state statutes that need addressing must be any state firearms-related law that's created solely from federal references. I have always opposed law created this way, the danger being that the federal legislature could simply change the referenced federal statute(s), which would effect (enact new) state law. When the feds realize this vulnerability, they could use the referenced statutes to expand on law to further nullify a state's SAPA.
If we want to keep such laws, we should instead specify the offenses directly in our statutes and remove all references to the federal statutes.
