Illinois’ firearm restraining orders, known in other states as “red flag laws” or “extreme risk protection orders,” are civil orders that temporarily remove firearms from individuals who are a potential danger to themselves or others. These laws aim to prevent firearm injury through a removal of means from persons experiencing a temporary crisis. Data suggest firearm restraining orders have been infrequently employed in Illinois since the law’s enactment in 2019. Nationally, initial research suggests that these types of laws are associated with reductions in firearm suicide. However, national findings have not conclusively shown a significant reduction in firearm assaults attributable to these laws. As the majority of these laws have been passed relatively recently, more research is needed as data become available on their usage and outcomes.
