She's not the only oneImage | Amanda Trebach & George Retes compositeCaption: U.S. immigration enforcement agents have arrested dozens of American citizens amid the Trump administration's deportation campaign, including ICU nurse Amanda Trebach, left, and army veteran George Retes, right, both from the Los Angeles area. (Unión del Barrio and George Retes/Institute for Justice)Amanda Trebach, an intensive care nurse who has been trying to keep her migrant patients safe from immigration raids, never expected American law enforcement to use the same kind of violence against her, a U.S. citizen.But video filmed and posted by fellow organizers(external link) during one confrontation with U.S. Immigration and Customs Enforcement (ICE) in August shows Trebach forced to the pavement and roughhoused by federal agents, who violently arrest and detain her."You don't know who they are. They don't identify themselves. There's no due process,” she told CBC News.The incident occurred as Trebach and other members of a Los Angeles activist group called Harbor Area Peace Patrols had been circulating images of licence plates on nondescript vehicles to alert migrant communities to their presence.On Aug. 8, volunteers were photographing ICE agents leaving a staging site for raids on Terminal Island, whose Japanese residents were the first in America to be displaced and forcibly detained(external link) in internment camps during the Second World War.WATCH | 'They’re scared to go out and get groceries,' activist says of migrants:Media Video | Caption: Amanda Trebach, an ICU nurse and activist with Harbor Area Peace Patrols, says migrants from local communities are avoiding hospitals because masked agents have been known to patrol around them and other public institutions, looking for people to arrest, detain and deport.Open full embed in new tab (external link)Loading external pages may require significantly more data usage than loading CBC Lite story pages.Shortly after, the officers stopped their vehicle and jumped out; Trebach says they knelt on her head, handcuffed her and threw her into the back of a black van.She says ICE “kidnapped” her and told her to stop taking photos.“I just said, ‘Let me go. We're here. It's our right to monitor you,’” said Trebach. “I'm a citizen.”Trebach was released without charge hours later.“As is her constitutional right, Amanda was documenting the movements of the masked kidnappers,” Harbor Area Peace Patrols’ parent organization, Union del Barrio, wrote in a social media post(external link) detailing Trebach’s detainment.ICE officers themselves have leaned into characterizations of their arrests as abductions. In an incident two weeks later, agents were videotaped taunting Peace Patrol activists(external link) from their van saying, “Good morning ladies! A-kidnapping we will go.”Trebach is hardly the only U.S. citizen arrested and detained without charge. In a recent investigation, ProPublica found that more than 170 U.S. citizens have been detained(external link) by immigration enforcement as of Oct. 5.University of California in Los Angeles law professor Jonathan Zasloff says ICE has effectively been operating with “impunity” despite the growing cases of U.S. citizens and legal immigrants getting caught up in their raids.“They could break all these constitutional rights and nothing could happen to them,” he said.WATCH | ICE now largest U.S. police force:Media Video | The National : Caption: U.S. President Donald Trump’s immigration crackdown is supposed to be targeting criminal illegal immigrants, but more American citizens and legal immigrants are being rounded up.

Within two minutes, dozens of agents advance across the road, unleashing tear gas on the crowd of demonstrators.After smoke from the tear gas can be seen engulfing his car, Retes, in an account of his arrest(external link), writes that despite having identified himself as a citizen, ICE agents "smashed my driver-side window, and pepper-sprayed my face" as "others stood by and watched."“Even though I’m just complying, an agent puts his knee on my back and another agent puts his knee on my neck. And as they’re doing that I’m just telling them I can’t breathe,” Retes, 25, told CBC News.WATCH | George Retes says he was choked, arrested by ICE:Retes said this kind of behaviour seems to contravene U.S. laws.“The constitution is right there," he said. "I mean, that’s everything we stand for.”In a statement, ICE claimed(external link) Retes was “violent and refused to comply with law enforcement,” and blocked agents by “refusing to move his vehicle out of the road.” But ICE did not address why agents escalated the matter so quickly.WATCH | 'I can't breathe': U.S. army veteran recalls his arrest by ICE:Media Video | Caption: Security guard George Retes says he was just ‘trying to get to work’ when he found himself caught between an ICE raid and a counter-demonstration.

Among those arrested were four U.S. citizens(external link), charged with assaulting or resisting officers.Retes was held for three days before being released. He was in such a state of distress over what happened that the detention facility put him on suicide watch, he told The Associated Press(external link).Retes missed his daughter’s third birthday while locked up, he said, and is now suing the federal government for unconstitutional detention(external link). He has not been charged.“It's just crazy that all this can happen," he said. "But it doesn't change what the flag stands for or what it means to be an American.”Image | George Retes California veteran U.S. flags Institute for JusticeCaption: George Retes, a 25-year-old U.S. army veteran, was arrested by ICE agents on his way to work as a security guard at Glass House Farms in Ventura County, Calif., on July 10. While dismayed that this could happen even to U.S. citizens like him, he says 'it doesn't change what the flag stands for or what it means to be an American.' (Institute for Justice)ICE operating with 'impunity'Tricia McLaughlin, a spokesperson for the Department of Homeland Security (DHS), said(external link) ramped-up immigration enforcement is removing the worst kind of “criminal illegal aliens” off U.S. streets and sending a message: “Self-deport or we will arrest and deport you.”Survey data from February 2024 to March 2025(external link) shows about one-third of Americans agree that immigrants in the country illegally should be deported — though most believe arrests should not happen in places like schools and hospitals.Masked immigration enforcement agents have arrested people in and outside of public institutions — including hospitals(external link), schools(external link) and courthouses(external link) — on multiple occasions. This has caused some migrants to avoid medical care out of fears they’ll be detained, including at the hospital in South Los Angeles where Trebach works.“What Trump is doing is placing fear in the communities,” Trebach said. “They're trying to make us fearful so they can take over more power.”Image | Immigration Raids Los AngelesCaption: California Highway Patrol officers detain protesters on June 10 in Los Angeles. ICU nurse and migrant activist Amanda Trebach says it's part of an effort to 'make us fearful so they can take over more power.' (Eric Thayer/The Associated Press)There is also an explicit mandate for ICE officers to arrest as many people as possible to meet Trump’s mass deportation quota of 3,000 people a day, or over a million a year.In June, California Gov. Gavin Newsom decried(external link) the “chaotic federal sweeps” across his state to meet an “arbitrary arrest quota” that is “reckless” and “cruel.”Based on government figures from last year(external link) showing the number of immigrants with criminal convictions and pending charges being tracked by ICE, the administration is about 350,000 “illegal aliens” short of its target.Social media accounts, websites(external link) and even dedicated apps have documented sightings of immigration agents across the country, including a widely used phone app called ICEBlock.Under pressure from the administration, Apple and Google removed ICEBlock from the app store earlier this month. Apple told the app’s creator(external link) it had violated the company’s policies because “its purpose is to provide location information about law enforcement officers that can be used to harm such officers individually or as a group.”Image | Immigration Raids CaliforniaCaption: People pray in Los Angeles as they gather to protest immigration raids and the presence of ICE in their communities on July 1.
