As I noted yesterday, early reports of mass shootings are subject to the fog of war. Initial details are incomplete or wrong. We already have some substantial revisions to what happened when the shooter initially entered the school. As I noted, the first reports suggested that the gunman had shot his way past three officers — one school police force officer and two municipal police officers. The picture now looks significantly different — though the overall picture, I would argue, is much the same.

According to the latest reports, a school security officer exchanged gun fire with the shooter prior to the shooter entering the school. The two municipal police officers exchanged gunfire with the shooter once he was already in the school but — apparently — before he had actually begun shooting kids. They apparently felt they were outgunned. So they called in backup.

Here is the part of the story that is new and deeply disturbing. Apparently police on the scene waited for a significant period of time — like tens of minutes — while parents outside the schools begged them to go in and kill the shooter. Parents even brainstormed about whether they should go in and rush the shooter themselves since the mass shooting was unfolding as everyone waited outside.
