That is certainly not the case for federal, state, and local law enforcement authorities tasked with preventing domestic terrorist attacks.
While most attacks have been disrupted or failed on their own, 11 attacks since 9/11 have resulted in 33 deaths – including 13 people killed by Nidal Hasan at Fort Hood, Tex., in 2009. The Times Square bombing attempt by Pakistan-born Faisal Shahzad could have brought the total deaths due to domestic terror attacks much higher if the bomb had not failed to explode when ignited.
According to professor Mr. Kurzman’s analysis, 75 percent of the Muslim-Americans engaged in terrorist plots in 2010 were disrupted in an early stage of planning.
“This is consistent with the pattern of disruption since 9/11,” he writes, when 102 of 161 plots – 63 percent – were disrupted at an early stage of planning.
On Tuesday, Colleen LaRose – the Philadelphia woman who called herself “Jihad Jane” – pleaded guilty to four federal charges, including conspiracy to murder a foreign target (Swedish cartoonist Lars Vilks, who had depicted the Islamic prophet Muhammad in ways that many Muslims found offensive), conspiracy to support terrorists, and lying to the FBI.
