Final answer:
A search warrant is not always needed as there are certain exceptions where a search can be conducted without one, such as consent, probable cause, or emergency situations.
Step-by-step explanation:
A search warrant is not always needed. There are certain circumstances where a search can be conducted without a warrant. One such circumstance is when there is consent from the individual or property owner. For example, if a person gives consent to a police officer to search their car, a warrant is not necessary. Another circumstance where a warrant may not be needed is if there is probable cause, which means there is enough evidence to reasonably believe that a crime has been committed. In some emergency situations, such as the risk of evidence being destroyed, law enforcement may also be able to conduct a search without a warrant.
