Omaha ? A member of a Kansas church that protests at soldiers’ funerals has filed another lawsuit, accusing Sarpy County prosecutors of violating her constitutional rights.

The federal lawsuit is the latest filed by Shirley Phelps-Roper, who was arrested in 2007 during a protest at the funeral of a National Guardsman in Bellevue. Authorities say she let her then-10-year-old son stand on an American flag and she wore a flag as a skirt that dragged on the ground.

Phelps-Roper’s lawsuit says Sarpy County Attorney Lee Polikov, as well as other prosecutors in the office, violated her constitutional rights “by investigating her for protected expressive activity,” among other things.

Polikov said Monday he had not seen the lawsuit and could not comment specifically on it.
