Surprised?

Reading the about the latest mass murder, the killing spree and Northern Illinois University yesterday, I am struck by how surprised the media makes out everyone to be about how this could happen. People, you better get used to it. It's going to become a very common occurence.
There are a certain percentage of people with faulty brain wiring. Bipolars, sociopaths, pedophiles, or people who just enjoy killing or hurting others. That percentage probably stays fairly steady. So why the increase in these kind of incidents?
Easy. The world population continues to GROW at a steady rate.
The world population:

1961......3 billion
1974......4 billion
1987......5 billion
1999......6 billion
2011......7 billion (projected)
2024......8 billion (projected)
2042......9 billion (projected)

So even as the percentage of defectively brain wired people stays the same, the ABSOLUTE numbers of these people increase significantly. And they are in closer and closer contact with the rest of us. So more opportunity for adverse contacts.

So get used to events of this type. They will happen more and more frequently in the future.
