Understanding your Fourth Amendment Rights

As an American, you have certain fundamental rights, as guaranteed by the United States Constitution. Among them is the right to privacy and protections against search and seizure, as given in the Fourth Amendment. Let’s help you understand more fully your Fourth Amendment rights.

Certain rights to privacy were granted when the Fourth Amendment was added to the Constitution in 1791, which makes them over 225 years old. Designed to support the belief that “every man’s home is his castle,” the amendment says:

“The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.”

Fourth Amendment Protections

Such Fourth Amendment protections mean police cannot search your home or your vehicle without an arrest warrant or search warrant, without your permission or without probable cause that such a search would produce evidence in a crime.

That means if you were walking along a street and were stopped by police, officers would not have the right to search you unless such criteria were met. Indeed, police cannot randomly stop and search anyone without probable cause, a warrant or permission.

This also means that if police stopped your vehicle for a routine traffic violation, they would not have the right to search your vehicle based on that fact. Rather, police would have to have probable cause that a crime had been committed and evidence was in the vehicle.

Police Still Can Search You, Your House & Your Car

Though the Fourth Amendment provides many protections, it doesn’t cover everything. Police still can search you, your house or your car under certain circumstances. Such searches may be deemed “reasonable” under the law.

The ability of police to conduct a search also depends on where the search is conducted.

Police Can Search Your Car

Police are more likely to have the legal right to search your car than your home, since courts consider drivers to have less expectation of privacy on public streets. But car searches still depend on certain circumstances, including these:

  • An officer at an international border can conduct routine stops and searches of vehicles (United States v. Montoya de Hernandez, 473 U.S. 531, 1985).

  • After a valid traffic stop, police can let a narcotics detection dog walk around the exterior of the car without probable cause (Illinois v. Cabales, 543 U.S. 405, 2005).

  • If police have probable cause to believe a car is involved in criminal activity, they can search the car (Arizona v. Gant, 129 S. Ct. 1710, 2009).

  • Without probable cause, or belief of criminal activity, police can conduct a “pat-down” of a vehicle’s occupants after a lawful traffic stop (Arizona v. Johnson, 555 U.S. 323, 2009).

  • A state can use highway sobriety checkpoints to detect drunk drivers (Michigan Dept. of State Police v. Sitz, 496 U.S. 444, 1990) but cannot make detection of illegal narcotics the primary purpose of such checkpoints (City of Indianapolis v. Edmond, 531 U.S. 32, 2000).

Police Can Search Your Home

Police also can search your home under certain circumstances. These include:

  • Police can search a home if indications of criminal activity are in plain view (Maryland v. Macon, 472 U.S. 463, 1985).

  • Police can search a home if they have probable cause and there are “exigent circumstances,” meaning police have probable cause but lack sufficient time to obtain a warrant (Payton v. New York, 445 U.S. 573, 1980).

  • Police can search a home if such a search is incident (pertinent) to a lawful arrest (United States v. Robinson, 414 U.S. 218, 1973).

  • Police can search a home if the owner or occupant grants consent to such a search (Davis v. United States, 328 U.S. 582, 1946).

Police Can Search You

Police also can search you under some circumstances. These include:

  • If police observations of a person’s unusual conduct lead to a reasonable conclusion that criminal activity may be involved, police can stop that person and make reasonable inquiries to confirm or dispel such suspicions (Minnesota v. Dickerson, 508 U.S. 366, 1993, and Terry v. Ohio, 392 U.S. 1, 1968).

  • School officials do not need a search warrant to search a student who is under their authority, as long as such a search is reasonable under the circumstances (New Jersey v. TLO, 469 U.S. 325, 1985).

More Exceptions to the Fourth Amendment

Still more exceptions to the Fourth Amendment have arisen in recent years as the federal government has asserted increasing authority to protect national security, and as technological advances have made more information recordable and available.

For instance, the Department of Justice can access the records of millions of Americans with only subpoenas, not search warrants. (A subpoena is a government order for a citizen to provide something and may be issued by government agencies without a court’s approval.)

Also, the National Security Administration (NSA) routinely spies on citizens without warrants or probable cause, all under the guise of “national security.”

fourth amendment rights

But the nation’s security still must be weighed against an individual’s right to privacy. This recently occurred when the Supreme Court ruled that police cannot search the contents of a cell phone without a warrant (Riley vs. California, 2014).

You Still Have Legal Rights Against Searches

So despite many exceptions to the Fourth Amendment, you still have legal rights which protect you against unlawful searches. Such rights can be determined by an experienced criminal defense attorney.

If you face a criminal charge stemming in part from police conducting a search of you, your car or your home, let Neal Davis explore whether your constitutional rights were violated and any evidence found is invalidated.

He focused on listening and helping, not just explaining his fees
Client needed representation for a child sex abuse case that was complex and needed an attorney who understood the full extent of the law.

" Neal represented our son and the case against him was dismissed, while other attorneys we consulted primarily focused on explaining their fees and pushed us to settle. Neal took time to understand our needs and truly appreciate our values and to convey to the Court, the District Attorney and the Judge the true essence of the case details and the circumstances of how our son was himself victimized, versus treating us as another case. He saw the case through to the utmost extent of the law, so our son, who is an honor student, was completely exonerated, and he made sure that support and professional help were in place during the experience. He declined the court's offer of a 2-year probation and pushed harder with the D.A. even though we had already paid him his fees. Most attorneys would have simply walked away at that point; however, Neal wasn't satisfied with the results and had the case reset since he knew it was not a fair result for my son. In the end, the case was dismissed. "

He doesn't give up, no matter what you're up against
Client's child sex abuse case was dismissed

" This man saved my life from false imprisonment. Neal's belief in 'liberty and justice for all' as laid out in the Constitution of the United States, and especially as that principle relates to constitutional rights regarding the receipt of a fair trial, coupled with his refusal to quit fighting, are attributes of a noble spirit and a man of high character. When I interviewed Neal to defend me against very serious false accusations and criminal charges that followed, his candor about what I was up against and his real interest in my general welfare made choosing him to defend me a 'no brainer.' Hiring Neal after hearing Dick DeGuerin say 'Neal is a real fighter' was the best decision I could have made and this was after interviewing a number of attorneys. He cares about people, truth, and justice; an attorney who will not give up; a man who will defend the rights of anyone accused of a crime with every fiber of his being to ensure fairness and the protection of our legal rights."
