It’s obvious that jail isn’t good for the jailed. It may be particularly bad for people accused of minor crimes, who are confined not because they are likely to be dangerous but because, under our cash-bail system, they can’t afford to get out. Think of the appalling case of Kalief Browder, the Bronx teenager who was profiled by my colleague Jennifer Gonnerman, in 2014. He was charged with stealing a backpack and spent three years at Rikers Island awaiting trial. Two years after the trial was dismissed and he was released, Browder killed himself.
