After weeks of chaotic immigration raids in public and at workplaces across Southern California, a judge has granted a temporary restraining order in a lawsuit, requiring federal authorities to find “reasonable suspicion” to make immigration arrests in California’s central district, including Los Angeles, and preventing them from using characteristics like race or speaking Spanish as the sole basis for arrests.

The federal judge found the Department of Homeland Security has been making arrests in Los Angeles immigration raids without probable cause. The ruling comes after federal immigration agents arrested approximately 200 migrants in a pair of chaotic raids at legal marijuana farms on Thursday, according to the Department of Homeland Security. Conflicting accounts from workers and federal officials have raised a flurry of questions as DHS officials say their agents were shot at.

The developments again thrust a spotlight on a region that emerged weeks ago as an epicenter of large-scale immigration operations by the Trump administration – and of tense protests against the actions that often yielded arrests of their own.

Demonstrations were planned again Friday in Los Angeles, as labor and faith leaders and immigrant rights advocates push back against deportation operations heralded by the Republican White House. The mayor also signed an order aimed at protecting immigrant communities.
