Heavy penalties for child pornography offenders have also come under fire. Many judges are refusing to apply the Guidelines in these cases. It has been argued that the Sentencing Guidelines actually increase unwarranted sentencing disparities. Joseph S. Hall writes, "Factors such as whether or not the defendant can afford a skilled attorney capable of making innovative legal arguments or performing detailed factual investigations have a profound influence on a defendant's sentence. The prosecutor's power to extract guilty pleas, previously held in check by judges, is now counterbalanced only by the diligence of the defense attorney." William J. Stuntz claims that "when necessary, the litigants simply bargain about what facts will (and won't) form the basis for sentencing. It seems to be an iron rule: guidelines sentencing empowers prosecutors, even where the guidelines' authors try to fight that tendency ... In short, plea bargains outside the law's shadow depend on prosecutors' ability to make credible threats of severe post-trial sentences. Sentencing guidelines make it easy to issue those threats." The federal guilty plea rate has risen from 83% in 1983 to 96% in 2009, a rise attributed largely to the Sentencing Guidelines. Sentencing table The sentencing table is an integral part of the U.S. Sentencing Guidelines. The Offense Level (1–43) forms the vertical axis of the Sentencing Table. The Criminal History Category (I–VI) forms the horizontal axis of the Table. The intersection of the Offense Level and Criminal History Category displays the Guideline Range in months of imprisonment. "Life" means life imprisonment. For example,
