The Los Angeles County Board of Supervisors is moving forward with an effort to create "ICE-free" zones, prohibiting immigration enforcement officers from being on county-owned spaces.

The board voted unanimously Tuesday to instruct county counsel to draft an ordinance for the board's consideration within 30 days.

The measure, led by Supervisor Lindsay Horvath, would prohibit agents from staging, processing or operating in such areas, if it receives final approval, according to The Los Angeles Times.

“Los Angeles County will not allow its property to be used as a staging ground for violence caused by the Trump administration,” Horvath said.

Horvath said that since ICE's deployment to Los Angeles in June, “federal immigration enforcement has too often escalated into extreme violence.”

The vote came after an ICE officer last week fatally shot Minneapolis resident Renee Good in a confrontation with ICE agents.  The Trump administration said the agent shot Good in self-defense as she attempted to run him over with her vehicle. Critics question whether the agent's life was in danger and the lethal force was justified.
