The Decline of Violence: Scientific American

It appears that many in the world feel that violence has been increasing and that we are much more unsafe today than people were 50, 100 or 500 years ago.  According to this article in Scientific American, that isn't true.

The Decline of Violence: Scientific American:

I think part of the reason for the public opinion of increasing violence, is that we are more aware of the violence that does occur, because of the tremendous improvement in international news reporting, with video and graphic detail.  Many of the occurrences of violence would probably have never even been discovered, let alone reported in previous decades or centuries.  Family violence, for example, happened, but was accepted, and nobody seemed concerned about it.

Also, I think there are "vested interests" in publicizing the violence that occurs.  The news industry has found that reporting of violent acts increases readers/listeners/viewers, and thus revenue.  The police, judicial, and military industries and their associated lobbies would like to keep the awareness up so they can increase their budgets, numbers of personnel, and/or sell more tools or weapons.
