Several hundred gun rights activists rallied at Washington’s capitol Saturday to protest the new voter-approved law that requires background checks for person-to-person gun sales and transfers. Most participants in the "I Will Not Comply" rally were openly carrying handguns or rifles or both.

There are two gun initiatives on the Washington ballot. Initiative 594 and Initiative 591 both have to do with background checks on gun buyers.

The battle over the initiatives is a classic fight between gun control advocates who say more regulation will limit gun violence and gun rights activists who fear a loss of their Second Amendment “right to bear arms.”

Bill and Melinda Gates have each contributed $25,000 to the campaign to require background checks for most gun sales in Washington. The couple’s personal contributions late last month helped push the Yes on Initiative 594 campaign over the $1 million mark.
