Terrorism, both domestic and international, has become the bane of modern life in the United States. Just last month, the think tank Center for Strategic & International Studies issued a brief saying that terrorism would become worse in the U.S. in the coming year. This past February, the New York Times reported that the threat of domestic terrorism has outpaced that of Islamic extremism. As such, it is a mistake to underestimate the dangers posed by homegrown terrorists.
