Been to this park many times and never noticed the sign myself. Tri-City Herald article Richland men may sue city over gun ban in parks The Associated Press RICHLAND, Wash. -- Two Richland men say the city is breaking state law by banning weapons in parks. The two men, David Campbell and Bob Marguilies, told Tuesday's city council meeting they may file a lawsuit to force the city to change signs posted at parks. The Tri-City Herald reports the weapons ban is included on a sign at Howard Amon Park that also bans consuming alcohol and letting dogs run loose. Campbell says the gun ban violates a state attorney general opinion that cities lack authority to prohibit firearms in public places. In Seattle, Kent lawyer Bob Warden, is threatening a similar lawsuit. He announced he was carrying a gun Saturday when he went to a West Seattle community center where he was turned away.
