On August 30, 2006, a 19-year-old youth, clad in a trench coat, drove into the parking lot of his former high school in Hillsborough, N.C.--and began firing. Eight random shots wounded two students. When the police arrived, Alvaro Castillo gave up without a struggle. It was Castillo's second exploit involving firearms that day. Earlier Castillo had murdered his father in the family home.

Three months later in the small town of Emsdetten, Germany, 18-year-old Sebastian Bosse posted a video message on the Internet: "I can't f-kin' wait until I can shoot every mother-f-kin' last one of you." He then drove to his former school, armed with out-of-date rifles and homemade pipe bombs. Marching through the building, he shot randomly at students and teachers, injuring 37 people before ending his own life.
