It's important to remember that correlation is not proof - it doesn't necessarily mean that one part of the correlation is the cause of the other part(s).
Keep that in mind.

Another dubious first for America: We now employ as many private security guards as high school teachers — over one million of them, or nearly double their number in 1980.
And that’s just a small fraction of what we call “guard labor.” In addition to private security guards, that means police officers, members of the armed forces, prison and court officials, civilian employees of the military, and those producing weapons: a total of 5.2 million workers in 2011. That is a far larger number than we have of teachers at all levels.
What is happening in America today is both unprecedented in our history, and virtually unique among Western democratic nations. The share of our labor force devoted to guard labor has risen fivefold since 1890 — a year when, in case you were wondering, the homicide rate was much higher than today.5.2 million of us - it means that more than 1.5% of our total population is fully engaged in "protecting" the wealth of some Americans from other Americans.
