Granted, there is a widespread inconsistency in firearm  regulations among Colorado jurisdictions. This patchwork of laws  confuses people, who can unwittingly cross jurisdictional lines  without knowing they are breaking the law. To resolve this, the  proposed new law would preempt all municipal or county gun laws,  saying such regulation is exclusively a matter of statewide concern. This seems like a good idea on the surface. But while  it's one thing to curb Denver's confiscations of cars that pass  through the city bearing guns, it's quite another to tell  municipalities they can't regulate assault weapons, enact  safe-storage requirements and ban guns from their own school yards
