For what reason did Brian Encinia arrest Sandra Bland as noted in the book, Talking to Strangers: What We Should Know About the People We Don’t Know?

After noticing Bland's out-of-state license plates, Encinia decided to find a reason to pull Bland over, believing her suspicious. On the side of the Prairie View Highway, Encinia arrested Bland for failing to signal, threatening her and pulling her from her car. Though Encinia testified in court, saying the area was known for its high crime rates, Prairie View was a quiet college town.
