Via Ben Boychuk, I have this article out of Washington State about proposed gun control legislation there.
Responding to the Newtown school massacre, the bill would ban the sale of semi-automatic weapons that use detachable ammunition magazines. Clips that contain more than 10 rounds would be illegal.
But then, with respect to the thousands of weapons like that already owned by Washington residents, the bill says this:
In order to continue to possess an assault weapon that was legally possessed on the effective date of this section, the person possessing shall . . . safely and securely store the assault weapon. The sheriff of the county may, no more than once per year, conduct an inspection to ensure compliance with this subsection.
In other words, come into homes without a warrant to poke around. Failure to comply could get you up to a year in jail.
