“The cops can do almost anything they want, and often the most maddening tactics are actually completely legal. There are many reasons for this, but three historical developments stand out: the war on drugs provided the template for social control based on race; 9/11 gave federal and local officials the opportunity to ensnare Muslims (and activists) in the ever-increasing surveillance and incarceration state; and a lack of concern from the public at large means these tactics can be applied, often controversy-free, to anyone who resists them.”
