Walnut Creek police will need to update their use-of-force policies after Gov. Gavin Newsom signed a statewide ban on electric-shock gloves for law enforcement.

Newsom signed Assembly Bill 2760 on Tuesday, Sept. 29, according to the governor’s announcement. The law prohibits local, state and federal law enforcement agencies from using wearable electroshock devices anywhere in California. It takes effect in 2027 and expires Jan. 1, 2030.

The ban covers weapons designed to deliver electric shocks while worn as gloves. It excludes conventional Tasers, stun guns and similar devices held like pistols, according to the chaptered bill text.

The Associated Press reported that U.S. Immigration and Customs Enforcement had awarded a nearly $17 million contract to buy 6,000 pairs of the gloves.

Under the new law, every law enforcement agency in the state, including the Walnut Creek Police Department, must update its use-of-force policies to prohibit the devices. Agencies are also barred from using state funds to purchase them. The California Department of Justice must complete a study of their safety and community impacts and report findings and recommendations to the Legislature by Jan. 1, 2029, according to the state Commission on Peace Officer Standards and Training.

Assemblymember LaShae Sharp-Collins, who authored the bill, said ICE's contract was the catalyst but not the only reason.

"There's a lot of unrest and a lot of uncertainty," Sharp-Collins said in the Associated Press report published by Patch. "A lot of people are scared."

The law’s application to federal officers is disputed. Kevin Johnson, a professor emeritus at UC Davis School of Law, said courts are likely to rule that California cannot bar federal officers from using the gloves because the law probably conflicts with the Supremacy Clause of the U.S. Constitution, according to the same report.

California law enforcement groups broadly opposed the ban, the report said. Sacramento County Sheriff Jim Cooper, a Democrat and former state lawmaker, said the ban makes no sense because the gloves are among the tools officers can use.

First Assistant U.S. Attorney Bill Essayli, a Trump appointee, also challenged the state’s authority in an X post quoted in the report. "Governor, we've been through this already," Essayli wrote. "If you want to regulate federal agents, you have to win a federal election. Until then, you have no jurisdiction."
