The story made all the local news in the DFW area.
That makes sense, since the lawsuit won’t be able to be hidden from taxpayers there.
But apparently the story was widely covered by local news stations when it “broke” (it was covered repeatedly by my local stations in Kentucky), but angles like this one go uncovered. And the national network news is apparently not covering it, either. They know full well that public reaction would be very negative, and probably also that people generally don’t think the school and police acted unreasonably, so they don’t want to report on this lawsuit.
