MOORE, Okla. (AP) — With an ominous storm approaching, the Moore Public School District flashed a text alert to parents: “We are currently holding all students until the current storm danger is over. Students are being released to parents only at this time.”

Parents had a gut-wrenching choice, and only a few minutes to make it. Trust the safety of the seemingly solid school buildings and the protection of trained teachers and staff. Or drive frantically ahead of a massive tornado and attempt to take their children safely home.
