While the United States has not experienced a major terrorist attack since September 11, 2001, there have been continual terrorist attacks around the globe. According to the National Counter Terrorism Centers (NCTC) Worldwide Incident Tracking System (WITS), during 2004 there were only five terrorist incidents in the US (accounting for one injury). Conversely, during the same time period there were 3,192 terrorist incidents worldwide, resulting in 6,060 deaths and 16,091 wounded victims.
During 2004, 1,080 police officers were killed by terrorists and another 1,370 police officers were wounded by terrorists outside the US. Table one represents the number of officers killed and wounded versus the total number of people killed and wounded. The data seems to suggest that police officers who are victims of a terrorist act are much more likely to be killed (as opposed to wounded) than civilians who are victims of a terrorist act.
