The encryption debate that began with Apple and the FBI a few weeks ago is picking up steam. This is an issue without simplistic explanations. Here are two pretty good explainers if you or someone you know would like to understand it better.
The first is an article by Steven Levy, who wrote a book about the first round of Crypto Wars in the 90s. The second is a segment of Last Week Tonight with John Oliver. In his crass (warning: foul language ahead), amusing way he explains the encryption debate.
