It just might be better to leave the law the way it is. If you are armed and you KNOW that law enforcement intends to disarm you, you are in no doubt about the threat to your life.
If the bill passes, you can be sure that there will be law enforcement who will violate it anyway.
The existence of community wide emergencies does not trigger an exception to the Second Amendment; it is part of the reason that the Amendment exists at all.
What's needed is a law that makes clear that those who would disarm law-abiding citizens should be recognized as robbers and treated as such. Such a law would make everyone safer, including those who might otherwise be inclined to ignore a statute which merely affirms people's right to keep and bear arms, since it would make clear to the latter people the costs of lawlessness.
