Based on reasonable belief that a crime has been committed.

Explanation:

The Fourth Amendment protects Americans from actions by the Government that amount to unreasonable seizures and searches. The keyword here is Unreasonable. For a person to be protected under this amendment, the reason for the search must be ruled unreasonable by the law.

This means that searches and seizures must be conducted based on a reasonable belief that a crime has been committed. If arrested or subjected to a search without reasonable cause, this amendment protects the person and any evidence that may be acquired at this time is ruled inadmissible in court.
