Government Action Required for Unreasonable Searches and Seizures
The Fourth Amendment's protection against unreasonable searches and seizures is a limit on government, not on everybody.
11. Government Action Required for Unreasonable Searches and Seizures
The Fourth Amendment’s prohibition of “unreasonable searches and seizures” applies only to government actors.
- The Constitution does not constrain searches or seizures by private citizens, even if the private citizen turns over the fruits of a search or seizure to the government.
- The government may use the fruits of private searches and seizures in a criminal prosecution, even if a government agent could not have constitutionally conducted the same search or seizure.
- Government agents may not circumvent the constitutional protection by intentionally enlisting the help of private actors to conduct a search or seizure.
The Fourth Amendment limits government actors only. The threshold question is not whether a search was reasonable; it is who did the searching in the first place.
If a purely private person, a neighbor, a landlord, a private security guard acting on their own, rifles through someone's belongings, the Fourth Amendment simply does not reach that conduct, no matter how intrusive it was. The protection turns on who acted, not on how invasive the search was.
Here is the part that surprises people: the private person can then hand whatever they found to the police, and the government may use those fruits in a criminal prosecution. It does not matter that a government agent could not lawfully have done the same search; because no government actor conducted it, there is no Fourth Amendment violation to suppress.
There is one important limit that keeps this from becoming a loophole. The government cannot get around the Fourth Amendment by intentionally enlisting a private person to do its searching for it. If a government agent deliberately recruits or directs a private actor to conduct a search or seizure the agent could not constitutionally perform, the private actor is treated as an arm of the government, and the Fourth Amendment applies. So the question becomes whether the private party was truly acting on their own, or was instead doing the government's bidding at the government's instigation.
Ask who searched, not how invasive.
The Fourth Amendment limits government actors only; a purely private search is outside it.
Private finder, government user: a private party can search and hand the fruits to police, and the government may use them, even if an agent could not have done the same search.
The one limit: the government cannot intentionally enlist a private actor to do its searching; a recruited or directed private searcher is treated as the government.
A man ships a sealed package through a private courier. A courier employee, acting entirely on her own curiosity and against company policy, opens the package, finds what looks like stolen goods, and calls the police. An officer arrives, looks at what the employee has already exposed, and the goods are later offered against the man in a prosecution.
The evidence is admissible. Now change one fact: suppose an officer, wanting to avoid getting a warrant, asked the employee to open the package for him and she did so at his request. Now the employee was intentionally enlisted to act for the government, she is treated as a government actor, and the Fourth Amendment applies to the opening.
An option that suppresses evidence because the private search was intrusive, because the private party had no right to search, or because an officer could not have done the same search.
The protection turns on who searched; a purely private search is outside the Fourth Amendment regardless of intrusiveness, and the government may use its fruits even though an agent could not have done it.An option that applies warrant or reasonableness analysis to a genuinely private search, or that admits a search the government secretly orchestrated.
The amendment applies only to government action; a private search needs no warrant, but a government-instigated private search is treated as the government's.An absolute option, such as that the government may never use evidence a private party found, or that any search of private papers or property is unconstitutional.
The government may use private-search fruits, subject only to the enlistment limit; the outcome rests on government action, not on absolutes.An 'admissible' option keyed on the evidence's reliability or the suspect's lack of a privacy expectation rather than on the search being private.
Name the operative reason: no government actor conducted the search, so the amendment does not reach it.the stem gives you an intrusive search or seizure carried out by someone who is not obviously a police officer, a neighbor, a landlord, a private guard, an airline employee, and then has the government use what was found.
Before asking whether the search was reasonable, ask who did it.
If a purely private party searched on their own, the Fourth Amendment does not apply and the fruits are usable, however invasive the search.
The one thing to hunt for is government instigation: did an officer ask, direct, or recruit the private party to search?
If yes, the private party is treated as the government and the amendment applies.
Any option that suppresses a genuinely private search, or that admits a search the government secretly orchestrated, is a distractor.
A man's landlord, suspicious of unusual smells, let herself into his rented apartment while he was away, searched through his closet entirely on her own initiative, and found a locked box that she pried open to reveal what appeared to be stolen electronics. The landlord, acting without any contact with or direction from law enforcement, photographed the items and brought the photos to the police, who used them to build a case against the man. The man moved to exclude the evidence, arguing the search violated his constitutional rights.
Should the evidence be excluded?
A detective suspected a woman of possessing contraband but knew he lacked grounds for a warrant. He approached the woman's house cleaner and asked her to look through the woman's desk drawers the next time she worked and to report anything unusual. The cleaner did exactly as the detective asked, found a hidden ledger, and turned it over to him. The woman moved to suppress the ledger, arguing it was obtained in violation of her constitutional rights.
Should the ledger be suppressed?
A woman's coworker, acting out of personal suspicion and with no contact with the police, secretly went through the woman's bag at work and found a stolen company laptop. The coworker reported it to a manager, who called the police; the responding officer simply viewed and seized the laptop the coworker had already located. There was no police involvement of any kind before the coworker's search. The woman argued the laptop should be excluded as the product of an unconstitutional search.
Should the laptop be excluded?
A man dropped off a damaged hard drive at a private repair shop. A technician, following the shop's routine practice of checking files to diagnose problems and acting with no involvement from any officer, opened a folder and saw clearly illegal images. The technician called the police, who then viewed only what the technician had already found and used it against the man. The man sought to suppress the images as the fruit of an unconstitutional search.
Should the images be suppressed?
An officer wanted to see inside a locked storage unit but lacked probable cause for a warrant. He told the unit's private facility manager that he 'would really appreciate' it if the manager cut the lock and looked inside, and the manager, wanting to help the officer, did so and found contraband that he handed over. The manager would not have entered the unit but for the officer's request. The renter moved to suppress the contraband, arguing the search was really the government's.
Should the contraband be suppressed?
