Excited delirium

# Overview
Excited delirium is a controversial term used to explain deaths of individuals in police custody, in which the person being arrested, detained, or restrained is highly agitated and may be under the influence of stimulants.  The term is not recognized in DSM-IV, but has been listed as the cause of death by some medical examiners. There may also be a link between excited delirium deaths and the use of Tasers to subdue agitated people. 

# Excessive force
Some civil-rights groups argue that the term is being used to absolve police of guilt, in overly restraining people, during arrests. The cause of death only appears where police are involved in restraining individuals.    This does not include those deaths in chemical dependance treatment, EMS, hospital, or psychiatric care facilities who die while being restrained or while in seclusion.
Eric Balaban of the American Civil Liberties Union said: "I know of no reputable medical organization  certainly not the AMA American Medical Association or the American Psychological Association that recognizes excited delirium as a medical or mental-health condition."  Melissa Smith of the American Medical Association said the organization has "no official policy" on the disorder. 

# Symptoms

# Cases
Nathaniel Jones: his death while in custody of Cincinnati police was first attributed to excited delirium.  In a lawsuit over the death of Mr. Jones, some facts related to excited delirium were disputed. The defendants in the trial court proceedings asserted that: 1) the decedent was resisting arrest; 2) that reasonable force was used in an attempt to restrain him; and 3) that excited delirium was the cause of death. The plaintiffs claimed: 1) that the officers used excessive force; 2) that the decedent died from compressive asphyxia caused by police officers whose entire weight was on his body; 3) the decedent was not resisting but rather attempting to reposition his body so he could breathe. The trial court found that the plaintiffs sufficiently stated a claim of excessive force.
Toney Steele: one of the first high-profile cases involving question of excited delirium; died in San Diego in the back of a patrol car. 
Kevin Geldart: died after police, in an effort to restrain him, shot him multiple times with a Taser gun and sprayed him with pepper spray.
Roger Holyfield: the 17-year-old died October 29, 2006, the day after Jerseyville, Illinois police shocked him repeatedly with a Taser gun. "Holyfield died of natural causes after being restrained by the police, which occurred as a result of an episode of excited delirium," according to Jerseyville officials. 
Frederick Williams: died hours after police shocked him repeatedly with a Taser while in custody. After Williams' family announced they were suing, Taser International asserted that they would argue he died from excited delirium.
