California has banned law enforcement officers from using gloves that deliver electric shocks, the first such ban in the United States.

Governor Gavin Newsom signed the law on Tuesday as part of a package of more than 20 bills pushing back on federal immigration enforcement. The ban covers local, state and federal officers in California, takes effect next year and runs until 2030.

It comes weeks after US Immigration and Customs Enforcement moved to equip its officers with the gloves, awarding a nearly 17 million dollar contract for 6,000 pairs. The devices are designed to gain compliance from combative people.

Assemblymember LaShae Sharp-Collins introduced the bill to ‘put a pause’ on the devices while the state studies their risks. The law requires the Justice Department to report on their safety by 2029.

The Department of Homeland Security pushed back, saying immigration enforcement is a federal responsibility. The clash over policing tools in California continues.
