Thin on the right so far

Only 2 of the 27 outlets with a published leaning rating that ran this story are rated right.

This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.

U.S. District Judge Maame Ewusi-Mensah Frimpong has issued a preliminary injunction that restricts immigration officers from conducting warrantless arrests in Southern California. The order, granted on September 2 and unsealed on Wednesday, mandates that officers must assess the likelihood of an individual escaping before proceeding with an arrest without a warrant. This assessment must consider the totality of circumstances known to the agent or officer.

The lawsuit that led to this injunction was filed by the American Civil Liberties Union of Southern California, Public Counsel, and Los Angeles-based immigrant advocacy groups. The injunction applies to the Central District of California, which includes the counties of Los Angeles, Orange, Riverside, San Bernardino, Ventura, Santa Barbara, and San Luis Obispo. Judge Frimpong denied the government's request to delay the order.

Disagreement on documentation requirements

Washington Top News reported that Frimpong ordered the government to thoroughly document the probable cause leading to an arrest before a warrant could be obtained, stating that the mere fact of being in the country illegally is insufficient for a warrantless arrest. In contrast, a federal attorney cited by Washington Top News, Daniel Mummolo, stated there is no statutory requirement to document such assessments, and that different officers handle things differently. He referenced a memo from former acting director of U.S. Immigration and Customs Enforcement Todd Lyons that allowed officers to make an 'on-the-spot' determination about escape likelihood. Frimpong responded to this by saying the government had not presented evidence of officers stating they performed the assessment without writing it down.

Omissions

None of the right-rated digests mention the specific details about documenting probable cause or the government attorney Daniel Mummolo's statement regarding the lack of a statutory requirement to document escape risk assessments. The right-rated digests also do not include the specific names of all the plaintiffs' attorneys or the previous temporary restraining order that was lifted by the Supreme Court.

How each side covered it

Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.

Left

14 rated outlets

  • Nine of the 13 left-rated reports focused on the core ruling that federal judges have blocked immigration officers from making warrantless arrests in Southern California unless they determine the person is likely to escape. These reports highlighted the preliminary injunction granted by U.S. District Judge Maame Ewusi-Mensah Frimpong. Several mentioned the lawsuit was filed by the ACLU of Southern California and Los Angeles immigrant advocacy groups. The Seattle Times, The Independent, Associated Press News, The Independent (US), The Sun Chronicle, Bangor Daily News, and Palo Alto Online all used similar phrasing to describe the judge's order. Cal Matters stated the judge ruled federal immigration agents likely violated the Constitution by not assessing flight risk.

11 rated outlets

  • Eleven of the 12 centre-rated reports highlighted the restriction on warrantless immigration arrests in Southern California. These reports, including digests from Washington Top News, My Mother Lode, WBAL, The Standard-Journal, WPLG, WKMG, MyNewsLA.com, KESQ, Danville San Ramon, The Record, and Winnipeg Free Press, stated that a federal judge blocked immigration officers from making such arrests unless they determined the person was likely to escape. Washington Top News, as the only full report, provided more detail on the judge's reasoning, including the requirement for documentation and the consideration of the 'totality of the circumstances'. It also noted the lawsuit was filed by the ACLU of Southern California, Public Counsel, and Los Angeles immigrant advocacy groups.

Right

2 rated outlets

  • The two right-rated reports, Clarin and Madison Courier, both stated that a federal judge banned or blocked immigration arrests without a warrant in Southern California, except for the risk of escape. Clarin mentioned the order followed an ACLU lawsuit and seeks to stop detentions based solely on immigration status, demanding an escape likelihood assessment. Madison Courier used phrasing similar to many other outlets, stating the order follows a lawsuit by the ACLU of Southern California.
