DES MOINES, Iowa (AP) — Five Des Moines Black Liberation Movement protesters have filed a lawsuit in federal court seeking to block Iowa State Patrol troopers from arresting them for trespassing if they return to the Iowa State Capitol or property surrounding it. The four women and man were among 17 people protesting in support of the Black Lives Matter movement at the Capitol on July 1.

They were arrested after a scuffle broke with officers. They were told by troopers they couldn’t return, some for six months and others for a year. They claim the ban blocks their fundamental constitutional rights of free speech and assembly. A spokesman for the Iowa Attorney General’s office, which will represent the troopers, says they will respond in court.
