Officers have shown up to protests with riot gear, armored trucks, and military rifles. This is what America’s police now look like, and it’s the result of a decades-long buildup of military equipment among the country’s police departments. It began as a Reagan-era program to give police departments more resources to fight the War on Drugs, and has escalated ever since. Today, the idea of a militarized police force is baked into how American police see themselves.
