An Illinois state lawmaker has introduced a controversial bill that critics argue would effectively legalize attacks on police officers by individuals experiencing a mental health episode. Democratic State Representative Lisa Davis, who works as an attorney in the Cook County Public Defender’s office, introduced House Bill 3458 in February 2025. The bill has sparked widespread backlash, with opponents claiming it would endanger law enforcement officers and embolden individuals to act violently under the guise of mental illness.
The proposed legislation states that it would provide a legal defense for individuals charged with aggravated battery against a peace officer if the officer interacted with someone who a “reasonable officer” could believe was having a mental health episode. The bill applies specifically to individuals with a documented mental illness who act “abruptly” during such encounters.
Under current Illinois law, aggravated battery charges apply to attacks on peace officers, firefighters, private security officers, and other first responders. Davis’ bill, however, would create an exception for individuals with mental health conditions, effectively shielding them from prosecution in certain cases.
Critics, including law enforcement advocates and political opponents, have condemned the bill as “pro-criminal” and dangerous. A blog called Second Cop City, which focuses on Chicago policing issues, was among the first to report on the bill, stating, “If this passes, mental illness will be an excuse to attack and beat police officers. In fact, who wants to bet there will be thousands of people who suddenly have doctor notes that permit them to attack cops?”
The bill has garnered two co-sponsors, Democratic State Representatives Marcus Evans and Kelly Cassidy. However, it has also drawn sharp criticism from law enforcement officials and others who argue that it undermines the safety of police officers and could lead to abuse of the mental health defense.
Davis, whose husband is a firefighter, has faced additional scrutiny for excluding other first responders, such as firefighters, from the bill’s provisions. Critics have questioned why the bill specifically targets peace officers while leaving other emergency personnel unprotected.
The proposal comes amid ongoing debates about police reform and mental health treatment in Illinois and across the country. Supporters of the bill argue that it aims to address the complexities of mental health crises and reduce the criminalization of individuals struggling with mental illness. However, opponents fear it could have unintended consequences, putting officers at greater risk and complicating law enforcement responses to mental health-related incidents.
As the bill moves through the legislative process, it is expected to face significant opposition from law enforcement groups and Republican lawmakers. The debate over House Bill 3458 highlights the ongoing tension between criminal justice reform and public safety concerns in Illinois.
