Do you realize that America has an exploding criminal class? The incarceration rate in the United States remained basically the same from about 1925 to 1973. There was an average of a little over 100 people behind bars for every 100,000 residents of this country. By the year 2000 that rate had quadrupled, with almost 500 people incarcerated for every 100,000 residents. America has overtaken Russia as the world's most aggressive jailor. Approximately two million Americans are currently behind bars, with about four and a half million on parole or on probation. Another three million Americans are ex-convicts.
