At left, that’s Bob Warden of Kent, with the parks security employee who asked him to leave Southwest Community Center during his much-publicized challenge to the city’s parks-facility gun restrictions two weeks ago (here’s our coverage from that day). He said at the time he planned to file legal action as a result; now, he has, according to e-mail we just received from him, which included the complaint he says was filed in federal court this morning and served at Mayor Nickels‘ house. The mayor and the city are named as defendants, in Warden’s claim that the city rule violates the U.S. and Washington state constitutions. Read the entire 11-page document here. (City offices are closed so we might not get an official response today.)
