After the attacks of September 11, 2001, human rights observers raised concerns about increased police brutality in the U.S. An extensive report prepared for the United Nations Human Rights Committee, published in 2006, stated that in the U.S. the War on Terror "created a generalized climate of impunity for law enforcement officers, and contributed to the erosion of what few accountability mechanisms exist for civilian control over law enforcement agencies. As a result, police brutality and abuse persist unabated and undeterred across the country." The culture of impunity for police is reinforced by law enforcement operations with the FBI's Joint Terrorism Task Force, which undertakes "disruption" actions against suspects instead of investigations and criminal charges. During the "war on terror," there have been noted increases in enforcement power for officers. By 2007, discussion on the appropriateness of using racial profiling and force against people of color has decreased since 9/11. Racial profiling specifically increased for those of South Asian, Arab, Middle Eastern, and Muslim origins. An example of increased use of police use of force has been in the use of tasers. From 2001 to 2007, at least 150 deaths were attributed to tasers and many injuries occurred. People of color have been the main people who have been targeted the most with regards to increased taser use.
