Answer :
Final answer:
The Supreme Court upheld an officer's right to search a vehicle's trunk when they have probable cause, which is a higher standard than reasonable suspicion, and necessary for more invasive searches.
Explanation:
In the case of US vs. Carroll, the Supreme Court upheld an officer's right to search a vehicle's trunk when the officers have probable cause. Probable cause is the legal standard for determining whether a search or seizure is constitutional or a crime has been committed. It is a more stringent requirement than reasonable suspicion, which is only enough to stop and frisk individuals on the street under certain conditions as established in Terry v. Ohio (1968). However, for more invasive searches, such as those of a vehicle's trunk, officers must have probable cause to believe that evidence of a crime is present within the area to be searched.
