Arrest warrant is required if the suspect is at home and there is no emergency.

• A. Warrants are always required, even on public property.
• B. An arrest can only occur with a warrant.
• C. Arrests do not require probable cause.
• D. A warrant is required if suspect is at home and there is no emergency.

Answer: (D)

In-home arrests without an emergency require a warrant because the home has strong Fourth Amendment protections: absent exigent circumstances, police must obtain a warrant before entering to arrest someone. A warrant is issued based on probable cause, allowing lawful entry and seizure of the suspect inside the home. If there’s no emergency, entry and arrest in the home without a warrant would be unlawful, so the warrant becomes necessary.

In contrast, arrests can occur without a warrant in public places with probable cause, or when exigent circumstances exist (instant danger, risk of flight, destruction of evidence). Consent from the occupant can also allow entry and arrest without a warrant. The other statements misstate how warrants and probable cause work, whereas the described rule for an in-home arrest without an emergency is correct.
