For example: Officer Jones is investigating a robbery at the local supermarket. The cashier indicates that a patron named Mary Smith may have seen the robber. When Officer Jones interviews Mary, Mary makes statements implicating herself in the robbery as a lookout. Can Mary’s statements be used against her later, even though she was not read her Miranda Warning? The answer is yes, because Mary was not in custody when she was being asked the questions. Therefore, Mary was free to leave if she wanted to.

No. Before a court will even entertain the possibility that the search in question was unreasonable, the person being searched must have had a legitimate expectation of privacy. To determine whether the defendant had a legitimate expectation of privacy the courts will look at the following factors: (1) did the person subjectively or actually expect some degree of privacy, and (2) is the person’s expectation objectively reasonable, that is, one that society is willing to recognize?

EXAMPLE #1

The police install a hidden video camera in the shower area of a local fitness club. Most people who use the shower in their fitness club have a subjective expectation of privacy. Privacy in a shower area is an expectation that society is willing to recognize. Therefore, the installation of a hidden camera by the police in a fitness club’s shower area will be considered a search and subject to the Fourth Amendments requirement of reasonableness.

EXAMPLE #2

While John is making a telephone call in a glass enclosed phone booth; he places a bag of cocaine on top of the phone. A police officer walking by notices the bag and arrests John for possession of a controlled substance. At trial, John tries to argue that the search of the phone booth was unreasonable because the officer lacked a warrant. This argument will fail because the court will never even get to the reasonableness of the search.

When police find a bag of cocaine on the top of a phone in a phone booth, it is not a search for Fourth Amendment purposes. It is very unlikely that John would think that a public phone booth is a private place, and even if John did, society is not willing to extend the protections of privacy to public pay phones.

Example: Officer Doright observes Tom and Dick walking down the street. Officer Doright has a hunch that Tom and Dick are up to no good. Armed with nothing more, Officer Doright goes to the local judge and attempts to get a search warrant for the boy’s home. Should a judge grant the warrant?

No. A police officer’s hunch, with nothing more, will not satisfy the probable cause requirement. However, if Officer Doright observed Tom and Dick conduct a drug deal, then probable cause would likely exist for a warrant to search their home.

EXAMPLE: Officer Doright is standing in your doorway talking to you about the weather. While talking, Officer Doright notices a bag of cocaine and a sawed-off shotgun on your couch. Officer Doright can legally seize these items without a search warrant because they are in plain view.
