On Tuesday's show: Two school boards on Greater Houston’s west side have passed new library book policies. We learn what was decided at Fort Bend ISD and Katy ISD.

Also this hour: We saw a familiar face among the folks doing state-by-state roll calls at last week’s DNC -- actor Sean Astin. He visited Houston back in 2018 to discuss mental health. We revisit our conversation with him.

Then: Houston-based Halliburton suffered an apparent cyberattack last week. We discuss what steps businesses can take to ensure cybersecurity -- and how it affects the rest of us when that doesn’t work.

And we revisit the story of an all-Latino Houston homicide squad from the 1970s, which is the subject of a two-part docuseries called The Chicano Squad, airing Sept. 2-3 on A&E. We talk with comedian and actor Cristela Alonzo, who hosted Chicano Squad, a podcast that told that same story and was released in 2021.
