Mandatory sentencing takes away from the fair judicial process. Sure the courts are lessened with court cases that have run the gamut of making courts dockets overloaded. However, mandatory sentencing does not look at the facts and the issues of the case. Without looking at the issues, unfairness could exist.
Intentional murder in cold blood should get the death penalty. Pedophiles should get the death penalty. Serial killers should get the death penalty. Serial rapists should get the death penalty. And the death penalty should mean death. People would think twice before committing crime if the penalty was death and it was carried out.
