My heartfelt condolances go out to the family and friends of the Virginia Tech shooting victims, and to the family of the man who commited these acts. Its easy to forget that those who commit this type of violece leave behind a legacy of sadness for their own as well.

A couple questions/comments:

What is DARPA?

I have also heard that antidepressants were involved, as is often the case in these types of tragedies.

In World War II the US Army adopted the use of silhouette targets, instead of bulls eye targets, for rifle training. The reason was to get the soldiers past the natural human hesitation of killing another human being.

People don’t want to admit it but for some individuals video games can have the same effect.

The attacks have already begun. Calls for confiscation of guns (which, in England and Australia, has had the opposite of the intended efect), calls for 1 gun purchase per month laws (which Virginia already has), etc. But the fact is evil, violence, and mental illness exist independent of man’s laws. We already have laws against murder - if everyone would simply abide by that we wouldn’t need to worry about inanimate objects whether they be guns, knives, blunt objects or something else.
