Rodney King was the first break in the dam. The beating that sparked the rebellion in 1992 was not new. What was new was video cameras. Now everybody could see the unrestrained violence against the defenseless that America calls “law enforcement.” Consumer electronics have advanced. There are cameras in every phone. Video has now recorded the recent deaths Philando Castile and Alton Sterling. It did not record the less nationally known case of Henry Green V here in Columbus.
