On Nov. 27, exactly two weeks after the terrorist attacks that killed 130 people in Paris, FBI agents swarmed into a private home in Harrisburg, Pa. Their target: 19-year-old Jalil Ibn Ameer Aziz, an American citizen and Muslim whom they’d been watching for several months, largely through his postings on Twitter. Using as many as 57 separate accounts, Aziz had pledged allegiance to the Islamic State, called for the killing of non-Muslims, aided others to make hijrah to Syria to join the jihad there, and expressed his own wishes to do the same.
And if that weren’t enough, he promised further to continue the attacks against America, posting, for instance, “Know, O Obama, that we are coming to America, and know that we will sever your head in the White House.”
But as the FBI soon discovered, Aziz’s jihadist lust did not end with just words. At the home he shared with his parents in the Pennsylvania capital, according to the affidavit filed in the case, they found a “go-bag,” or knapsack, containing “five M-4 style high capacity magazines loaded with 5.56 ammunition, a modified kitchen knife with the handle removed and wrapped in cloth and string, a thumb drive, a tin filled with various over-the-counter medications, and a head wrap commonly referred to as a balaclava.”
