Public anger over health care reform has not quieted. The FBI is investigating similarities between the brick thrown through Rochester Democratic Headquarters and the one that crashed through the Niagara Falls office of a Congresswoman two days earlier. “I think it’s part of a pattern,” the Congresswoman says. A voice message threatening a sniper attack was also left on a campaign phone here. It was found in an office the Congresswoman rarely uses. Her main Rochester headquarters is at the Keating Federal Building. Visitors there must first pass through a metal detector. Other security measures there are slightly more subtle. Planters holding flowers are solid cement blockades which keep vehicles from barreling through the front door. Security guards now patrol 24 hours a day. The Congresswoman said she is comfortable with security in Rochester. “Niagara Falls is the one we’re really worried about,” she said.
