Sen. Tom Cotton's New York Times op-ed article arguing for using the military to police violent protests and riots in American cities has elicited no end of outrage over its publication. This misses an important point: Modern law enforcement already deploys many tools and tactics borrowed from the military.
This "militarization" of policing has a long and troubled history. Anyone hoping to change how police do their work is going to have to reckon with it — and, in particular, how racial fears informed this transformation of policing in the first place.
The key shift came in earnest after World War II. Los Angeles's William Parker was the archetype of the new breed of police chiefs. He had served during the war and became a captain overseeing the military occupation of areas conquered by the Allies. When he returned, he transplanted many of the methods he had learned overseas to his hometown.
Parker despised the idea of "community policing," where officers lived among the people they policed. For Parker, policing was more akin to an occupation. The result of his reforms was a far less corrupt police force than the one he had inherited, but much more militarized department. Unfortunately, it was also overwhelmingly white, which led to an increasingly strained relationship with a city that had become far more diverse by the 1960s.
This set Los Angeles up for disaster. In the Watts riots in 1965, Parker reacted the only way he knew how. He described policing rioters as akin to "fighting the Viet Cong," as if city residents angry over racial injustices were a bunch of communist guerrillas. His deputy and soon-to-be successor, Darryl Gates, began taking officers to a nearby Marines training camp to bone up on adopting counterinsurgency tactics to the streets of Los Angeles.
This marked a sea change in policing. The historian Tracy Tullis has described how a growing number of city police forces came to view their restive populations as "a Vietnam at home," one the police could only tackle by embracing the tactics and increasingly the weapons of their military counterparts. As race riots became more commonplace over the course of the 1960s, counterinsurgency tactics became all the rage.
In Los Angeles, Gates created the first Special Weapons and Tactics team, which quickly became a model for other cities. The members of these SWAT units, most of whom had served in either the Korean or Vietnam wars, spent their days learning what Gates himself described as "the history of guerrilla warfare, scouting and patrolling, night operations, camouflage and concealment, combat in buildup areas [and] ambushes."
At the request of the Kerner Commission, which studied the causes of the 1967 riots in Detroit, Newark and beyond, Gates devised a "model civil disturbance plan" that could be distributed to police departments across the country. He proposed that departments be reorganized along military lines, and that officers start reading military manuals: "The Guerrilla and How to Fight Him" as well as "Combat in Fortified and Built-Up Areas." (Gates also recommended reading guerrilla warfare manuals by Che Guevara and Vo Nguyen Giap because cops needed to "know thy enemy.")
