New Bill Would Stop Cops From Citing Debunked ‘Excited Delirium’ Syndrome

“The fact that the police are still using a pseudoscience diagnosis to justify the murders of people of color and communities of color is unacceptable,” said González-Rojas, a Democrat from Queens.

Excited delirium became popular in the late 2000s, when the manufacturers of Tasers and other tactical weapons pushed it as a way to explain deaths in police custody. The syndrome’s boosters link it to drug use and say it turns people into violent, super strong aggressors. They also claim it can lead to cardiac arrest. Its associated symptoms include agitation, disorientation, and rapid breathing — which can have any number of underlying causes.

“It has no basis in science,” said Joanna Naples-Mitchell, a research adviser for Physicians for Human Rights who has written about the history of excited delirium.

Along with police reform groups Campaign Zero and the Surveillance Technology Oversight Project, her organization began consulting medical and legal professionals two years ago to write language now included in the bill, Naples-Mitchell said. “The law is reflecting where the science is.”

González-Rojas’s bill would invalidate excited delirium as a defense in civil and criminal lawsuits. It would also prohibit public agencies and contractors from referencing the syndrome in reports, procedures, policies, death certificates, and autopsy reports.

After Rochester police killed 41-year-old Daniel Prude in 2020 by putting a hood over his face and pinning him to the pavement for two minutes, an autopsy report included excited delirium as a contributing factor in his death. The New York attorney general’s office, which tried and failed to indict the officers involved, later issued a report arguing that first responders “must be trained to recognize the symptoms of excited delirium syndrome and to respond to it as a serious medical emergency.”

By that time, the American Psychological Association had denounced the syndrome. The American Medical Association soon followed suit, decrying it as “justification for excessive police force, disproportionately cited in cases where Black men die in law enforcement custody.”

The state Office of the Attorney General declined to comment. The Rochester Police Department did not respond to a request for comment.

In 2020, when the largest protest movement in United States history fought against racism and police brutality, Prude’s name became a rallying cry. After an attempted cover-up, Rochester’s top police brass resigned, and advocates and reform legislators wrote Daniel’s Law, a bill that would order trained counselors, instead of police, to respond to people experiencing mental health crises in New York state.

The state Senate majority supports Daniel’s Law and is now pushing to fund a pilot version in this year’s budget. But the law would not touch excited delirium, allowing authorities to continue citing it.

González-Rojas’s bill seeks to fill that gap, following New York Focus’s reporting on NYPD training procedures. Through a public records request, New York Focus obtained training documents showing that the department instructs cops to consider deploying velcro restraining straps and pepper spray, which “will cause the subject’s eyes to involuntarily close, even if they are insensitive to pain.” The documents also showed that the department has attempted to establish connections between excited delirium and synthetic marijuana use.
