Several members of the group Veterans for Peace were escorted out of the Old South Meeting House in Boston Monday night after they attempted a citizen's arrest of former Defense Secretary Donald Rumsfeld.
"I went down in front and looked Donald Rumsfeld in the eye and said, 'I'm making a citizen's arrest,'" protester Nate Goldschlag told WCVB-TV.
"He lied us into Iraq. He lied about weapons of mass destruction. He lied about Saddam Hussein being involved in 9/11."
Three of the protesters removed from the event were with Veterans for Peace and a fourth was a member of Code Pink. One protester was arrested outside the event for allegedly using a bullhorn to assault a police officer.
Most of the 300 people who had to buy a copy of Rumsfeld's book, "Known and Unknown," to attend the event appeared to be fans.
"He's one of the greatest Americans that has ever lived," one woman said.
