Because American cops are on the front lines in counterterrorism, the Terrorism Prevention and Response topic page is updated with news and information to protect the homeland from all enemies, foreign and domestic. From lone wolf domestic terrorists to radical Islamist jihadists, terrorism existed in the U.S. long before 9/11 and will remain a looming threat.
The mastermind behind the 9/11 terrorist attacks has been killed. The United States is in possession of his body and has confirmed his identity using familial DNA, according to reports. Killed in Pakistan
