The once-famous Roy Cohn has faded from the public consciousness, but the lawyer had a hell of a career, beginning with doing his part to destroy America alongside Joseph McCarthy and ending with doing his part to destroy America by representing a young Donald Trump. The documentary Where’s My Roy Cohn? spends much of its runtime examining Cohn’s arrogant, confrontational, and self-promoting public image, making a strong case that Cohn’s shiftiness and shittiness paved the way for today’s political belligerence. Cohn was also gay, though he never came out (he died from AIDS-related causes in 1986, shortly after being disbarred for unethical conduct), and his relationship with Ronald Reagan, even as Reagan ignored the AIDS crisis, is just one of a dozen eye-widening, stomach-sinking elements in director Matt Tyrnauer’s film. But by the time Cohn’s crazy, furious tale ends, one’s feeling isn’t of enlightenment so much as weary resignation: Terrible people have always existed, and they’ve always helped other terrible people be terrible, and a whole lot of these terrible people are also very powerful. Ugh. Sigh. Fuck all these motherfuckers.
