Under which circumstance can a search be justified according to legal standards?

A search can be justified when a search warrant is issued based on probable cause because this process involves a judicial oversight that establishes a reasonable belief that a crime has been committed and that evidence of that crime will be found in the location specified in the warrant. The requirement of probable cause serves as a safeguard against unreasonable searches and ensures that law enforcement acts within the boundaries of the law.

In contrast, public outcry might indicate community concern but does not meet the legal standard needed for a search. Similarly, merely hearing noises from inside a property does not, on its own, establish probable cause necessary for a warrant. Lastly, while information obtained from social media can be useful in investigations, it must be corroborated and supported by additional evidence to justify a search. Therefore, the issuance of a search warrant based on established probable cause remains the most legally sound basis for conducting a search.
