Kendrick Johnson case: First a tragedy, then a travesty

Kendrick Johnson died horribly in a rolled-up mat in a south Georgia high school gym. Local and state investigators ruled the death an accident. But a deep racial distrust in the system has fueled rumor, conjecture and conspiracy theories. And they are carried far and wide by social media.

Someone has to pay for this tragedy, and the family of a white FBI agent has become the target. The feds came in, one might suppose, to get to the bottom of what happened. But that investigation is 28 months — and counting — and has no sign of ending.
