The Tucson shooting in which six people were killed and 14 others injured is what law enforcement officers call an “active shooter attack,” says the Wall Street Journal. The New York Police Department issued a report to security officials with its analysis of 202 such incidents in the U.S., dating back to 1966. Historically 98 percent of the active shooting incidents were carried out by a single attacker. That “makes these attacks more difficult to detect before they occur,” said Jessica Tisch of the New York police counter-terrorism unit.
Tisch said 29 percent of the shootings occurred in schools, 23 percent in malls or other commercial settings, 13 percent in office buildings, 13 percent in factories or warehouses, and 22 percent in other places. The median number of deaths in these incidents was two. Some 46 percent of the attacks were ended by use of force, either by law enforcement or bystanders. In 40 percent of the cases the attacker committed suicide. Capt. Michael Riggio recommended that corporate business security officials prepare drills on active shooting attacks and create a “safe room” stocked with medical supplies. Riggio says that during an active shooting attack employees should never approach the arriving police officers; when evacuating, they should never hold anything in their hands. “Hands empty, hands open and hands up,” Riggio said.
