“There was no physical evidence of a crime, and the victim had no memory of one occurring. Fifteen years ago, Richmond and Mays would have escaped suspicion: before smartphones and Twitter, rumors floated around high schools and then dissipated, often before adults knew what was real and what was adolescent imagination. As it was, the evidence was limited to tweets, the photograph of Richmond and Mays carrying the girl, and a cell-phone video recorded late on the night of the parties and then uploaded to YouTube.” The New Yorker’s Ariel Levy has written a very interesting story of crime, adolescence, and online vigilantes in the digital age: Trial By Twitter.
