Eye witness reports say that the shooter did indeed chain two classroom doors so that students could not get out while he was walking the hall.

Not CLASSROOM doors - building doors. That's why officers were "standing around outside" while the shooting was happening - they couldn't get into Norris Hall because the building doors were chained shut from the inside.

I don't remember how the doors at Norris are, but if they're like Burruss next door, it's 2 doors side-by-side, like we have at Grundy. From the inside, you open the door by pushing on a bar that runs across the door about waist high. An 8' chain can be wrapped around the handles to lock the doors from the inside.

Chaining classroom doors would have been too time consuming and served no purpose. Chaining them before he opened fire would have greatly limited his "impact area"... afterward would have been too time consuming and not really necessary. Diff. people have said he walked into the classrooms or came back to a classroom when he heard people talking.
