MADISON, Wis. (AP) – Civil rights attorneys are trying to convince a federal judge the state’s Capitol access policy is unconstitutional.        Gov. Scott Walker’s administration adopted rules in December 2011 requiring anyone who wants to hold a Capitol event or rally to obtain a permit. The policy defines a rally as a group of at least four people gathered to promote a cause.  The American Civil Liberties Union filed a lawsuit in February arguing the policy violates free speech guarantees and doesn’t serve any legitimate government interest.  ACLU attorney Laurence Dupuis told U.S. District Judge William Conley during a hearing Wednesday the policy is content-based and vague. Assistant Attorney General Maria Lazar countered Capitol Police need to know how many people are in the building.  It’s unclear when Conley might rule.
