Imagine that a person is charged with a serious crime. The evidence against him is pretty good. If it goes to trial, there is a fair chance that the jury will have at least one reasonable doubt and vote not guilty. The prosecutor believes the person should spend at least 2 years in prison. However, the minimum sentence is only 18 months. Given these facts the prosecutor wants to plea bargain the case. The prosecutor really wants the defendant to serve 2 years.
In order to get a plea bargain, could the prosecutor offer the defendant better food when he/she does his/her time? What about a large private cell? What about free college education when in prison?
