The United States Sentencing Guidelines provides federal judges with a set of guidelinesto calculate an appropriate and "reasonable" sentence in criminal cases. These guidelines are intended to encourage fair and consistent sentencing proportionate to the magnitude of the crime committed. In most cases, sentencing guidelines suggest a range of months to years of prison time, in addition to a period of supervised release. Other sentences may call for a period opf probation, or a number of hours of community service. However, when the defendant in a criminal action is a corporation or similar organization, the recommended sentences must change. It’s impossible to put a corporation in jail (though individual employees or members may be co-defendants and may face prison time for their own charges).
