Twenty-five years after the passage of the Americans with Disabilities Act (ADA), people with disabilities are regularly dying at the hands of police officers across the country. In just the last few weeks, four such deaths have made national news: Kristiana Coignard in Texas, Antonio Zambrano-Montes in Washington, Lavall Hall in Florida and Charley Robinet in California. According to the American Psychological Association, some officers spend more time “responding to calls involving mental illnesses than they do investigating burglaries or felony assaults.” Too often, these encounters turn violent. Our best guess is that about 50 percent of killings by police involve psychiatric disability of some sort.

On March 23, the Supreme Court will have a chance to address this national crisis. The case of Sheehan v. San Francisco offers the justices the chance to clarify how the ADA applies to law enforcement — an important step that could strengthen the broader movement for police reform. This case will determine to what extent police can be held accountable to the best practices of their profession.

The case

In August 2008, Teresa Sheehan, a resident of a group home for people with psychiatric disabilities, threatened a social worker with a kitchen knife. The social worker called the police. Two officers arrived and entered Sheehan’s room but retreated when she threatened them as well. They called for backup. Instead of waiting, they re-entered the room. Sheehan came at them with the knife, and they shot her repeatedly. Luckily, she survived. A hung jury resulted in a partial acquittal of assault charges against her.

The lawsuit focuses on the legality of the second entry into Sheehan’s room. She sued the officers under Title II of the ADA, arguing that by not waiting for backup, the officers did not reasonably accommodate her disability. Furthermore, her attorneys argue that the violation of the ADA exempts the officers from qualified immunity, a doctrine intended to protect police from lawsuits unless it’s clearly established that the officers violated the Fourth Amendment’s prohibition on unreasonable search and seizure. At issue is not whether the police were wrong to enter the room the second time but whether it’s allowable for Sheehan’s lawyers to argue that they were wrong before a civil jury.

A federal judge initially dismissed Sheehan’s claim, but the 9th Circuit Court of Appeals reversed the decision, allowing the civil lawsuit to go forward. Now the Supreme Court will hear the case.

The arguments

Deputy City Attorney Christine Van Aken argues that the case is very narrow. She agrees that law enforcement must consider the ADA but that there’s a direct threat exemption that makes the officers’ second entry to the room lawful. Police had to enter because Sheehan could have had weapons or hostages or could have escaped via a window or fire escape. None of these things were true, but one legal position is that if an officer might reasonably have been concerned about these possibilities, Sheehan would have no claim.
