Our nation is founded on the idea that the law is impartial, that legal cases are won or lost on the basis of evidence, careful reasoning and nuanced argument. But they may, in fact, turn on the camera angle of a defendant's taped confession, the number of photos in a mug shot book, or a simple word choice during a cross-examination. Until we address these hidden biases head-on, the social inequality we see now will only widen, as powerful players and institutions find ways to exploit the weaknesses of our legal system. Unrated.
