GAO: Mt. Rushmore vulnerable to terrorism

Via the Counterterrorism Blog is an interesting Government Accountability Office (GAO) report issued this month entitled "Homeland Security: Actions Needed to Better Protect National Icons and Federal Office Buildings from Terrorism."  The report notes that Mt. Rushmore "could be targeted for symbolic reasons and for the purpose of harming people" and that "Information from Interior shows that these and other assets are vulnerable to attack in a variety of ways."  The report discusses Mt. Rushmore at length on pages 24-27 and a pdf copy can be accessed here.
