Some of Lori Andrews are challenging and potentially explosive. Is it valid to expect judges to refrain from “friending” lawyers they work with? Should sitting jurors be prevented from using social media? If a parent once wrote on Twitter that he or she didn’t want children, should that statement be admissible in custody hearings? As she weighs these topics, Andrews uses hundreds of anecdotes for illumination. She is particularly provocative on the dangers of data-mining technologies. What if our online searches for antidepressants or bankruptcy lawyers were to make their way to insurance companies or banks?
