Under the Fourth Amendment, warrants must be based on what standard?

• A. Reasonable suspicion
• B. Probable cause
• C. Consent
• D. No warrant required in all cases

Answer: (B)

Probable cause is the standard required to obtain a warrant under the Fourth Amendment. It means there must be a fair probability that evidence of a crime will be found in the place to be searched or that contraband or other items subject to seizure will be found there, based on the facts available to the authorities at the time the warrant is sought. This threshold is higher than a mere hunch but not a certainty, and the judge or magistrate must be convinced by sworn testimony or affirmation that the likelihood of finding something described is real. The warrant must also describe with particularity the place to be searched and the items to be seized. Reasonable suspicion is not enough for a warrant; it supports only brief stops or detentions. Consent can remove the need for a warrant if someone with authority freely agrees to it. There are exceptions to the warrant requirement, such as exigent circumstances, but the general rule remains that a warrant is issued based on probable cause.
