Since the shooting Virginia Tech has spent $10.4 million in security revisions

The Collegiate Times is not so impressed:

So far Virginia Tech has spent $10.4 million in security revisions.
These include, but are not limited to, the alert system which I, and many others I know, did not get on Tuesday's test, installing doors that cannot be chained shut, locking down the dorms even though they were locked when the incident took place last year, and adding 10 more officers to the Virginia Tech police, making the student to officer ratio 500:1 if all are on duty at once.

Last week as I heard the lists of defenses put in place and the manner of how a door locks, I recalled my World War II history.

In France there was the Maginot Line, a series of pillboxes and artillery placements connected by tunnel that ran the length of the border between Germany and France.

A defense so feared that the Germans simply went through the Arden forest in Belgium, going around the line and capturing Paris.

In some ways I wonder if we are creating our own Maginot line, building a set of defenses we feel is so strong that they will ward off any attacker.

The point I'm trying to make is that a lot of the new systems in place, which are all very good ideas, will act in the end act as only a buffer. . . .
