The push for gun control in Washington didn't stop in the state Legislature.

Seattle Mayor Mike McGinn is now pushing business owners to go gun free. He apparently is frustrated that lawmakers in Olympia didn't pass gun control legislation and wants to take matters into his own hands. He teamed up with Washington Ceasefire on Monday to announce a voluntary program for businesses to become "gun free zones."

Businesses can sign up online to participate and put a "gun free zone" sticker in their windows. Petitioners are collecting signatures for two gun initiatives that would go to the Legislature in 2014, who will then decide if the issue should go to the voters. One measure is backed by gun rights activists and would make it illegal for government to confiscate guns and create a database that goes beyond any national mandate. The other requires background checks for all gun sales, even private transactions.

Washington Ceasefire lists 28 businesses that have already signed up to be "gun free."

Critics say it just opens the businesses' doors to criminals.
