A California gun safety bill introduced on Wednesday would require parents to disclose if guns are kept at their homes and would require searches of a student’s personal property on campus if there is a credible threat. The bill is aimed at prioritizing student safety and helping prevent school shootings.

Senator Anthony Portantino decided to introduce the legislation after the Nov. 30 shooting at Oxford High School, where a 15-year-old suspect killed four students. The suspect, Ethan Crumbley, allegedly used a handgun his parents bought for him earlier that month. “We saw what inaction does in Michigan,” Portantino said. “Inaction leads to a tragedy. By empowering school districts with information and the mandate to investigate, we’re taking that inaction off the table.”

The proposed bill would require the California Department of Education to consult with the Department of Justice to create “model content” for schools to use when there is a threat or perceived threat of a deadly incident.

If a school is aware of a threat of a mass shooting, the school must report the threat to law enforcement and launch an investigation and threat assessment, which includes looking at the family’s firearm disclosure form. The school, in consultation with law enforcement, must search the student’s belongings, including car, locker, and backpack, for firearms.

Further, parents of students would be required to disclose if guns are kept at their homes and provide details on the firearm’s ownership, storage, and accessibility. Schools would need to provide parents with educational material on the safe storage of firearms in an annual notification.

“When in approximately 68% of school shootings the firearm was taken from the student’s home, friend, or relative, California needs to move the needle and take prudent public safety steps to address this problem,” Portantino said in a statement Wednesday. “We must move from threat assessment to protective action without hesitation.”
