They claim now the controversial language was a mistake.  

Senator Ed Murray and other Washington state legislators are back peddling fast away from controversial Senate Bill 5737 after it was "discovered" the bill contained the following language:

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.
SB 5737 is a gun-control bill being pushed by Washington state Democrats for what they are calling safe storage of weapons.    
The bill blew up in the face of Senators Ed Murray and Adam Kline, who claim they should have vetted the bill more carefully. The question is, who inside the state capitol believes it's within the governments right to search your home (even if it is only once a year) to determine your guns are properly stored?
What's even more alarming was the other provision stripped from the bill that said if a homeowner refused they could face a year in jail!
The Washington Times reported Wednesday the issue came to light, partly, because a self-professed Liberal lawyer raised concerns about citizen rights violated:

The Seattle Times reports that Seattle trial lawyer Lance Palmer first raised doubts about Senate Bill 5737 to the newspaper, complaining: They always say, 'We’ll never go house to house to take your guns away. But then you see this, and you have to wonder.'

 SB 5737 will still prohibit the sale of semi-automatic weapons that use detachable magazines. Also, clips that hold more than ten rounds would be prohibited.
Democrats are blaming staff who they claim misinterpreted what they were trying to do!
