Which selection would NOT fall into Fourth Amendment protection?

The selection that does not fall into Fourth Amendment protection is the lobby of a hotel open to the public. The Fourth Amendment protects individuals against unreasonable searches and seizures, but this protection primarily applies to areas where there is a reasonable expectation of privacy.

In the case of a hotel lobby that is open to the public, individuals do not have a reasonable expectation of privacy because it is accessible to anyone. The general public can enter and observe the activities in this space without any restriction. This means law enforcement can enter and gather information without constituting a search under the Fourth Amendment.

In contrast, spaces that are private, such as a fenced backyard, a locked garage, or an office that requires keycard access, afford a higher expectation of privacy. These areas typically have restrictions that limit access to the general public, thereby granting the occupants an expectation that their privacy will be protected under the Fourth Amendment.
