Police arrested nine people taking part in an antiwar march at the Republican National Convention on Sunday after they crossed a security fence into a restricted area near Xcel Energy Center. The nine were arrested for trespassing, said Doug Holtz, a St. Paul police commander. Eight of the nine protesters were taken away in handcuffs. The ninth, a 78-year-old nun, was not cuffed. The protesters had planned ahead of time to cross the fence, and organizers had announced it ahead of the march, which drew about 250 people. "We are going to march into the arms of police. Whatever they are going to do is all right with us," organizer David Harris, 73, said to the marchers before they entered the restricted zone. He was one of those taken away. All but one, who did not have identification, were soon released by police.
