This episode features Peter, Rhiannon, and Michael from the 5-4 podcast analyzing INS v. Delgado, a 1984 Supreme Court case about immigration enforcement and Fourth Amendment protections.

The case arose from two 1977 Immigration and Naturalization Service raids on a California garment factory, where armed agents positioned themselves at exits while others questioned workers about their immigration status throughout the facility.

Workers who were U.S. citizens or legal residents sued, claiming the raids violated their Fourth Amendment rights against unreasonable searches and seizures, but the Supreme Court ruled 7-2 that no constitutional violation occurred because it wasn't technically a 'seizure.'

Factory Raid Tactics: Armed Agents Block Exits While Questioning Workers

INS executed warrants based on general suspicion that the factory employed undocumented workers, without naming specific individuals suspected of violations.

"Several agents position themselves near the building's exits while other agents dispersed throughout the factory to question most employees at their work stations" - agents displayed badges, carried walkie-talkies, and were armed.

Workers who gave "unsatisfactory responses" or admitted non-citizenship were handcuffed and arrested, while agents told others they would return for follow-up questioning.

Rehnquist's 'Reasonable Person' Test: No Seizure Despite Blocked Exits

Chief Justice Rehnquist argued that a "reasonable person" would feel free to leave despite agents blocking exits, calling the raids mere "surveys" involving "simple questioning."

The majority opinion isolated each police action rather than considering the "totality of circumstances" - examining questioning, exit-blocking, and armed presence as separate non-threatening elements.

Rehnquist buried evidence in a footnote that an agent "attempted to prevent a worker from leaving" and the worker "punched the agent and ran away," dismissing it as an "ambiguous isolated incident."

Constitutional Rights Gaps: No Miranda Protections in Immigration Context

Unlike Miranda v. Arizona which requires police to inform suspects of their Fifth and Sixth Amendment rights during custodial interrogation, no similar protections exist for immigration enforcement.

"Why shouldn't the cops just have to fucking tell them" they're free to leave rather than forcing civilians to guess whether Supreme Court precedent considers their detention reasonable - Peter.

The burden falls on factory workers to determine their legal status during armed raids rather than requiring agents to clarify voluntary versus mandatory interactions.

Powell's Concurrence: Immigration Raids as Border Checkpoint Equivalents

Justice Powell compared factory raids to border checkpoints upheld in US v. Martinez-Fuerte, arguing both serve the "huge public interest in controlling illegal immigration."

Powell devoted half his concurrence to describing undocumented immigration as a crisis, estimating "between 2 and 12 million illegal aliens" justify constitutional exceptions.

The concurrence explicitly endorsed general warrant-style enforcement, allowing raids based on workplace suspicion rather than individualized probable cause requirements.

Brennan's Dissent: 'Studious Air of Unreality' in Majority Opinion

Justice Brennan criticized the court's "sleight of hand" that ignored the "far different story" told by the record of intimidation and coercion during the raids.

Brennan argued the decision creates a "cast and underclass of wage workers who have fewer rights" when U.S. citizens work alongside undocumented immigrants - Michael's interpretation.

The dissent noted that constitutional protections depend on social class, with lower-wage workers subject to "government surveillance and government harassment" regardless of legal status.

Fourth Amendment as Collective Right: Rethinking Constitutional Framework

Michael argues the Fourth Amendment protects "the people" collectively rather than individual "persons" like other constitutional amendments, requiring different legal analysis.

Current jurisprudence treats each police interaction atomistically - "if they're all zeros, you can add them up and you still get zero" - rather than considering cumulative state harassment.

A collective rights framework would make cases like stop-and-frisk "so much cleaner" to analyze as "widespread abuse of the population" rather than requiring statistical proof of individual violations.
