Sen. Rand Paul (R-Ky.) wrote in a TIME op-ed today that the crisis in Ferguson, Mo., after a police shooting underscores the need to demilitarize the police.

“If I had been told to get out of the street as a teenager, there would have been a distinct possibility that I might have smarted off. But, I wouldn’t have expected to be shot,” Paul wrote of the “awful tragedy” that took the life of 18-year-old Michael Brown. “The outrage in Ferguson is understandable—though there is never an excuse for rioting or looting. There is a legitimate role for the police to keep the peace, but there should be a difference between a police response and a military response.”

“The images and scenes we continue to see in Ferguson resemble war more than traditional police action.”

Paul cited a Glenn Reynolds piece in Popular Mechanics five years ago, stressing that our fears about police militarization are becoming reality.

“Washington has incentivized the militarization of local police precincts by using federal dollars to help municipal governments build what are essentially small armies—where police departments compete to acquire military gear that goes far beyond what most of Americans think of as law enforcement,” the senator wrote, adding it’s “usually done in the name of fighting the war on drugs or terrorism.”

When you couple this militarization of law enforcement with an erosion of civil liberties and due process that allows the police to become judge and jury—national security letters, no-knock searches, broad general warrants, pre-conviction forfeiture—we begin to have a very serious problem on our hands.

“Given these developments, it is almost impossible for many Americans not to feel like their government is targeting them. Given the racial disparities in our criminal justice system, it is impossible for African-Americans not to feel like their government is particularly targeting them,” Paul continued.

“This is part of the anguish we are seeing in the tragic events outside of St. Louis, Missouri. It is what the citizens of Ferguson feel when there is an unfortunate and heartbreaking shooting like the incident with Michael Brown.”

The senator stressed that “anyone who thinks that race does not still, even if inadvertently, skew the application of criminal justice in this country is just not paying close enough attention.”

“Our prisons are full of black and brown men and women who are serving inappropriately long and harsh sentences for non-violent mistakes in their youth,” Paul wrote. “The militarization of our law enforcement is due to an unprecedented expansion of government power in this realm. It is one thing for federal officials to work in conjunction with local authorities to reduce or solve crime. It is quite another for them to subsidize it.”

“Americans must never sacrifice their liberty for an illusive and dangerous, or false, security. This has been a cause I have championed for years, and one that is at a near-crisis point in our country.”
