A 2014 FBI study of 160 active shooter events since 2000 showed a staggered increase over time, with the four most violent years occurring in the last five years of the survey. Some question the study, but if this is a real trend and not a fluke — a spike that will be followed by a drop in such incidents — then it is one not easily explained.
U.S. Army Specialist Iván López, the soldier suspected in a deadly shooting rampage at Fort Hood, is a father of four children and a former police officer who served 10 years on the force in his native Puerto Rico before taking leave to join the Army.
