Our Guard Down

Obviously, intelligence and security forces were not able to prevent the Boston bombing. While many attempted terror attacks have been successfully interdicted since September 11, 2001, no nation including the United States is able to counter every threat. Those that would perpetrate terror are creative, resourceful, resilient and more intelligent than we want to believe they are. They will continually test our defenses, and sadly, occasionally, those with murder in their hearts will succeed.
