Illinois Legislator Proposes Mental Health Defense for Assaults on Police Officers

In February 2025, Illinois Democratic State Representative Lisa Davis introduced House Bill 3458, aiming to amend the state’s aggravated battery statute. The proposed legislation would allow individuals experiencing a mental health crisis to use their condition as a defense if charged with aggravated battery against a police officer. Specifically, the bill states that if an officer responds to an incident involving someone reasonably believed to be undergoing a mental health episode, and that individual has a documented mental illness and acts abruptly, this could serve as a defense to aggravated battery charges.

The bill has garnered support from co-sponsors Representatives Marcus Evans and Kelly Cassidy and is currently under review by the Illinois General Assembly Rules Committee. Notably, the proposed defense would apply exclusively to incidents involving police officers, explicitly excluding other first responders such as firefighters and emergency medical personnel.

Critics express concern that this legislation could be misused, allowing individuals to claim mental illness as a justification for attacking law enforcement officers. Some fear that it might lead to an increase in assaults on police, with individuals potentially obtaining medical documentation to support such defenses.

Supporters argue that the bill acknowledges the complexities of mental health crises and emphasizes the need for appropriate responses when individuals with mental illnesses interact with law enforcement. They believe it could lead to more compassionate and understanding handling of such situations, potentially reducing unnecessary incarcerations of those with mental health issues.

As the debate continues, the bill’s progression through the legislative process will be closely monitored, reflecting broader discussions on balancing public safety with mental health considerations.
