11:27 - Teacher props locked door open
11:28 - Ramos crashes across street, starts shooting, police called
11:31 - School resource officer drives by Ramos, mistaking a teacher for the shooter after hearing call on radio
11:33 - Ramos enters school through door that teacher propped open
11:35 to 11:40 - Cops arrive and enter, are fired upon through classroom door, stop outside classroom door
11:50 to 12:03 - 19 cops gather in hall outside door
12:00 to 12:15 - Border Patrol tactical team members arrive and are kept out of school by local commander
12:03 - Teacher calls 911 and says where shooter is
12:15 - Teacher calls back and says some kids still alive
12:50 - Border Patrol enters and kills shooter.
I don't see any way to interpret this other than there was a crowd of cops in the corridor outside the room while Ramos was killing kids and the teachers. He clearly didn't enter and kill them all right away if the teacher (and some kids in the room) were repeatedly calling 911.
And what must the jackass who propped the door open (likely to avoid having to go through the "normal" entry procedure after stepping outside) be thinking right now?
