As a Houston arbitrator and former appellate justice, Michael Massengale was the perfect lawyer for the Texas House investigatory committee to choose to help investigate and write the official report about that tragic day last May when so much went wrong and 19 children and two teachers were murdered. For the first time since the report was released, Massengale has given an in-depth interview to Texas Lawbook reporter Janet Elliott about his role in the investigation, the challenges he and the committee faced and his hopes for legislative improvements to police training and school safety.
