And that equipment has been used. In 1980 SWAT teams across America were deployed around 3,000 times. Deployments are estimated to have risen nearly seventeen-fold since, to 50,000 a year. Tactical police units are not just common in big cities: though nearly 90% of American cities with populations above 50,000 have SWAT teams, so do more than 90% of police departments serving cities with 25,000 to 50,000 people—more than four times the level from the mid-1980s. This tremendous rise in paramilitary police forces has occurred as violent-crime levels have fallen. And while SWAT teams remain essential for high-risk and dangerous situations, most SWAT teams are deployed to serve routine drug-related warrants on private homes, often with disastrous consequences.
