The Hughes Amendment to the Firearm Owner's Protection Act closed the federal registry of full-auto firearms post-1986. Naturally there is an exception for full-auto weapons possessed by law enforcement agencies; but how is this exception implemented? Are law enforcement weapons not required to registered at all? Are they added to the federal NFA registry? Are there two registries, one for law enforcement weapons and another for non-law enforcement? Does any provision of federal law require that such weapons be destroyed or collected by the BATFE if they're decommissioned?
The focus of these questions is whether the law-enforcement exception to the Hughes Amendment could be used as a back-door to get automatic firearms into the registry, and then have these weapons be transferred by the normal NFA process to private individuals. If it could be done, I could see a few Second Amendment- friendly sheriffs departments thumbing their nose at the Hughes Amendment and even maybe making it a source of department funds.
