TBO said, "WTF! Man, sometimes I'm afraid we are done as a race!"
Actually, I'm getting to the point where this really doesn't surprise me. I could come out with a simplistic answer where he's been taught by what goes on in the action movies he sees, or some of the TV shows, but I think that's only a small part of it.
In the early 1960s, there was a two part article in the Scientific American. Most of the stuff they wrote about was miles above my head, but sometimes, there was an article even I could understand.
Anyway, there was one where they described an experiment with rats. They placed them in a fairly large cage with a constant supply of food and water. It neither got smaller or larger. it stayed the same regardless of the population of rats. Of course, rats being rats doing what rats do, the population grew. As the population grew, things began to happen. Rats began attacking other rats. Eventually, they actually formed a loose gang type system, running around and randomly killing other rats. Female rats began aborting their young or killing them after they were born. Some rats became literally homosexual. maybe it should be called ratosexual, but I think you get the point. There was even cannbalism.
If this seems to be similar to what is going on in our society and th world today, think about it.
Eventually the population reached a point where the murders, disease etc. brought the population well below the original starting point and things resturned to normal. When the population increased again, the same thing occurred.
Consider a bell curve. You have a curve shaped like a bell. About half way up that bell you draw a straight line across the curve. Consider that line the optimum population level. As long as the population is at or below that level, things are normal. Once the population passes that level, that's when the trouble starts. As it get higher than the optimum level, conditions get worse until something drastic happens to reduce the population of rats.
Methinks the population of people is going though the same sort of what went on during that experiment.
That's my idea in the short and simple version.
