In the wake of the shooting in Uvalde, Texas, that left 19 children and two teachers dead, legislators in Washington, D.C., and across the country are debating “red flag” laws or extreme risk protection orders, or ERPOs.

Such orders, known in California as gun violence restraining orders, or GVROs, are in place  in .

A new study from the  at �������ϲ����Ͽ� Davis examines case details and mortality records from the first three years of California’s , which went into effect on Jan. 1, 2016.

The “red flag” law allows law enforcement, family and household members, some co-workers, employers and teachers to work with a judge to temporarily remove access to firearms and ammunition from people at significant risk of self-harm or harming others.

Interpersonal violence

The  in , shows that GVROs were used most often by law enforcement officers to prevent firearm assault and homicide. About 80% of GVROs were used in cases of threatened interpersonal violence.

Mass shooting threats — a threat to shoot an unspecified number of people or more than three people — occurred in almost 30% (58 cases) of all GVROS during this period. Six of the cases involved minors, all of whom targeted schools.

Among the individuals who had firearms temporarily removed with a restraining order, almost 30% had an assault-type weapon such as an  or AK-style rifle.

GVROs were also shown to potentially be effective in preventing self-harm, which was threatened in about 40% of the cases. No suicides occurred among individuals who were subject to the restraining orders.   

‘Used as intended’

“Extreme risk protection orders or GVROs offer a common sense, popular and promising tool for firearm violence prevention,” said , lead author of the study and an assistant professor in the  at �������ϲ����Ͽ� Davis Health. “The findings suggest GVROs are being used as intended — to remove firearms from individuals threatening to harm themselves, their intimate partners, co-workers, classmates or the general public.”

Some other key findings:

• Law enforcement officers filed 96.5% of the GVROs. Filings by family and household members made up 3.5% of the cases.
• Of the cases that involved a threat to others, almost 30% were directed at intimate partners, 23% at random people, 20% at family members and about 9% at someone at school.
• People served with GVROs had a median age of 39 and were predominantly male (93.5%).

Methods

The researchers took information from 201 available court case files for GVROs issued during the first three years of implementation in California. They characterized the recipients of the orders, the case circumstances and GVRO process details. They also linked the subjects of the restraining orders to mortality records to evaluate post-ERPO outcomes.

The researchers noted one limitation of the study: They could not obtain court files for all GVROs issued during the first three years (2016-18). Of the 413 restraining orders issued during that period, they obtained records for 218. Of those, 17 were dropped because the provided case files did not include GVRO forms.

GVROs stopped shootings

Firearms are the most  in the United States. Many acts of firearm violence are preceded by implicit or explicit threats, including .

Despite these warning signs, law enforcement officers in most states cannot remove firearms from individuals at risk of violence who are not already prohibited from possessing firearms. California’s Gun Violence Restraining Order law was created to fill this legal gap.

“Based on the evidence available to date, we believe that ERPOs are effective and enjoy broad public support, including among firearm owners,” said , senior author of the study, director of the Violence Prevention Research Program and professor of emergency medicine at �������ϲ����Ͽ� Davis Health.

The is a multidisciplinary program of research and policy development focused on the causes, consequences and prevention of violence. Studies assess firearm violence, the social conditions that underlie violence, and the connections between violence, substance abuse and mental illness. The program is home to the University of California Firearm Violence Research Center, which launched in 2017 with a $5 million appropriation from the state of California to conduct leading-edge research on firearm violence and its prevention.
