On Tuesday's show: President Donald Trump wants specialized National Guard units ready to deploy to U.S. cities to quell civil disturbances and ensure public safety and order. We discuss what that means, whether we could see troops deployed here, and whether this is largely a pretense to step up immigration enforcement.

Also this hour: A new Texas law expands when someone can be detained for psychiatric evaluation. Some welcome the change while others worry it crosses a line. We discuss the debate over involuntary treatment and its cost.

Then, a recent investigation by the Texas Observer explores the murky legal world of some private foster and adoption agencies.

And we meet a competitive Scrabble player.
