The only helpful thing I can think of is a change in school architecture.

And I admit its expensive and not very helpful.

Last night I heard a teacher interviewed on ABC who was talking about hiding in a bathroom 2' x 3' with 16 students for an hour while believing that the shooter was going to come in and shoot them all through the door.

The shooter apparently shot through the glass to get into the school.

He was able to get into 2 classrooms and kill students before they had time to hide or call for help.

The ones he did not kill had already run away or hidden. But they would have been safer if there were safe bullet proof rooms built into the schools.

Sorry, that's all I can think of.

1. A determined killer would make the 'safe room' his first destination.

Get people as they arrive and work his way back.

It's not a bad idea, maybe, but not enough, as you already indicated.

2. A safe room in every classroom.

It would have to be done when the school was planned.

Easier and cheaper than changing the violent mindset of a society in love with its guns.

3. I have designed several elementary schools.

I have designed several elementary schools. Modern school design has very much been influenced by security concerns but it also driven by energy conservation and the need to provide an environment conducive to learning. A simple thing like requiring bullet resistant laminated glass below a certain level would be a good deterrent assuming the proper floor plan is already in place to control unauthorized entry. The last two schools I designed had a security vestibule that was electronically locked in an emergency. I would really hate to see schools emulate prisons.
