No Kings Day Protest: Marines Detain Civilian in LA, Controversy Erupts

The “No Kings Day” protest wave on June 14, 2025, shook the United States. More than 1,500 cities—including Los Angeles—became the stage for resistance against excessive power and Trump administration policies. However, all eyes turned to Los Angeles when, for the first time in history, active-duty Marines detained a civilian on US soil. This incident ignited massive controversy, raising questions about the limits of government authority and the civil rights of US citizens.

Background: No Kings Day Protest

The No Kings Day movement stems from growing concern among Americans over authoritarian tendencies under President Trump. A massive military parade, held to mark the 250th anniversary of the US Army and Trump’s 79th birthday, was viewed by many as a “new king” display in a democracy. Over 1,800 cities joined the protest, from New York and Chicago to Los Angeles.

Major coalitions such as Indivisible, the ACLU, and 50501 mobilized mass action to remind the nation that people’s power is the true foundation of democracy. Under the slogan “No Kings,” protesters emphasized the need to reject concentrated power in the hands of one person or group.

Crisis in Los Angeles: Marines Detain Civilian

Los Angeles became the epicenter of tension following a series of unrests, particularly after immigration raids that led to clashes. The federal government responded by deploying roughly 700 Marines and over 4,000 National Guard troops to secure federal buildings across the city.

The controversy peaked when active-duty Marines detained a civilian, Marcos Leao, an Army veteran who inadvertently crossed a restricted line on his way to a Veterans Affairs meeting. Wearing headphones, he did not hear warnings from officers and was restrained with zip-ties for two hours before being released by LAPD without charges.

This marked the first time in US history that active Marines had detained a civilian on American soil. Many questioned whether this action violated the Posse Comitatus Act, which prohibits the use of the military for domestic law enforcement.

Legal Controversy and Public Reaction

The Marine detention immediately sparked responses from legal experts, state officials, and national politicians. California Governor Gavin Newsom and LA Mayor Karen Bass filed lawsuits against the federal government, accusing Trump of violating state sovereignty and congressional procedures.

Democratic senators such as Bernie Sanders and Chris Murphy condemned the use of the military to handle civilian protests. On the other hand, some conservative leaders argued that the government’s firm response was needed to restore order.

A national debate soon emerged over the limits of executive power, state sovereignty, and civil liberties. Many analysts argued that the administration’s actions threatened to shift the boundaries of American democracy.

Broad Impact and the Meaning of No Kings Day

The No Kings Day protest is more than a rejection of military parades or a single policy. It symbolizes Americans’ determination to safeguard democracy and prevent authoritarianism. The participation of millions nationwide reflects deep concern over the future of civil liberties.

The incident in Los Angeles stands as a reminder of the importance of public oversight when it comes to the use of domestic military force. This entire episode will be remembered as a crucial moment defining the meaning of democracy in the United States.
