Why do critics argue that plea bargaining can lead to punishments that are too lenient?

Critics of plea bargaining argue that the practice allows offenders to escape appropriate punishment for their crimes, thereby preventing justice from being served. This concern arises because plea agreements inherently involve concessions that result in less-severe outcomes than those typically handed down following a conviction at trial.123

Specifically, the process allows for:
* Charge bargaining: Defendants may plead guilty to reduced charges, such as pleading to assault rather than attempted murder.3
* Sentence bargaining: Defendants receive assurances of lighter or alternative sentences, such as "time served," in exchange for a guilty plea.3
* Count bargaining: Defendants facing multiple charges may have several counts dropped in exchange for pleading guilty to a smaller number of offenses.3

Because defendants who plead guilty often receive significantly shorter sentences—sometimes reduced by as much as two-thirds compared to those who exercise their right to a trial—opponents contend that the system prioritizes efficiency and the avoidance of risk over the imposition of just and proportional penalties.132
