Gun owners group vows to sue after Washington state passes tough new regulations

Washington state is on track to become one of the strictest states in the U.S. on gun laws.

Initiative 1639, a sweeping measure to beef up gun-regulations, passed Tuesday with 60 percent of the vote, Seattle's Q13 Fox reported. 

Campaign Manager Stephen Paolini, 22, said the measure’s passing sends “a message to our elected officials: Enough is enough.”

“My generation has been defined by gun violence. We have been defined by continued and repeated inaction by our elected officials,” Paolini told a crowd of supporters after the measure passed.

Alan Gottlieb of the Bellevue, Wash.-based Citizens Committee for the Right to Keep and Bear Arms, said opponents will sue to block I-1639. 

Other critics say I-1639 violates their Second Amendment rights and will be ineffectual in preventing mass shootings.
