Answer :
Final answer:
An arrest must be based upon probable cause, which is the justified belief that a crime has been or is about to be committed, a standard that's higher than reasonable suspicion.
Explanation:
An arrest must be based upon probable cause. This is the reasonable belief that a crime has been or is about to be committed. In cases where an arrest warrant is necessary, law enforcement officials must demonstrate to a judge that probable cause exists. Probable cause is also required for an officer to arrest someone without a warrant if they suspect a felony has been committed, and they can arrest individuals for misdemeanors witnessed themselves. Reasonable suspicion is a lower standard that allows officers to stop and frisk individuals if they suspect a crime is occurring, was committed, or will soon be committed, per the Supreme Court ruling in Terry v. Ohio (1968). However, reasonable suspicion alone does not justify an arrest; it may only lead to a temporary stop or detention.
