…research suggests that while it’s true that lawmakers passed a lot of measures calling for long prison sentences, if you look at how much time inmates actually served, not much has changed over the past few decades. Roughly half of all prisoners have prison terms in the range of two to three years, and only 10 percent serve more than seven years. The laws look punitive, but the time served hasn’t increased, and so harsh laws are not the main driver behind mass incarceration, either.
So what does explain it? Pfaff’s theory is that it’s the prosecutors. District attorneys and their assistants have gotten a lot more aggressive in bringing felony charges. Twenty years ago they brought felony charges against about one in three arrestees. Now it’s something like two in three. That produces a lot more plea bargains and a lot more prison terms.
I asked Pfaff why prosecutors are more aggressive. He’s heard theories. Maybe they are more political and they want to show toughness to raise their profile to impress voters if they run for future office. Maybe the police are bringing stronger cases. Additionally, prosecutors are usually paid by the county but prisons by the state, so prosecutors tend not to have to worry about the financial costs of what they do.

It couldn’t be because there are that many people doing bad things and we have better means of catching them and proving the cases, could it?
