In the first hours and days after the massacre at an elementary school in Uvalde, Texas, officials said they figured out how the gunman got into a building that was supposed to be secure.
“The exterior door,” the top police official in Texas told reporters, “was propped open by a teacher.”
That statement by Col. Steven McCraw, director of the Texas Department of Public Safety, would be quietly retracted within a few days. Instead, DPS officials said later, the door had been shut by the “teacher” but, for some reason, it didn’t lock even though it was supposed to do that automatically.
