The Club Q shooting has raised questions about what could have been done to prevent the mass violence, including whether the state’s red flag law could have been used to avert the attack. Colorado’s ERPO law, which stands for Extreme Risk Protection Order, means a family member or law enforcement officer can ask a judge to keep someone from having guns. We speak with CPR’s Andrew Kenney, who's been reviewing all of Colorado’s red flag filings since the law took effect three years ago. He found the use of the law varies greatly depending on the jurisdiction where the request is made.
