Plea bargaining in the United States
The constitutionality of plea bargaining was established by "Brady v. United States" in 1970, although the Supreme Court warned that plea incentives which were sufficiently large or coercive as to over-rule defendants' abilities to act freely, or used in a manner giving rise to a significant number of innocent people pleading guilty, might be prohibited or lead to concerns over constitutionality. "Santobello v. New York" added that when plea bargains are broken, legal remedies exist.
Plea bargain
Another situation in which an innocent defendant may plead guilty is in the case of a defendant who cannot raise bail, and who is being held in custody in a jail or detention facility. Because it may take months, or even years, for criminal cases to come to trial or even indictment in some jurisdictions, an innocent defendant who is offered a plea bargain that includes a sentence of less time than he would otherwise spend in jail awaiting an indictment or a trial may choose to accept the plea arrangement and plead guilty.
