In 2015, a young African-American woman, Sandra Bland, was driving in Texas when she was pulled over by a state trooper, Brian Encinia. What began as a routine traffic stop escalated into an altercation, which resulted in Bland's arrest. Three days later, she was found hanged in her jail cell.

Her death is the case that starts and ends Canadian journalist and bestselling author Malcolm Gladwell's new book Talking To Strangers, which seeks to parse why humans are so bad at understanding the people they do not know - and even those they think they do.
