What is a requirement for making a lawful arrest?

• A. Only suspicion of a crime
• B. Presence of a police officer
• C. The crime must have been witnessed
• D. A warrant must be obtained

Answer: (C)

Making a lawful arrest typically requires that the arresting officer has probable cause to believe that a crime has occurred. In many jurisdictions, this means that witnessing the crime can provide the direct evidence necessary for establishing that probable cause. Observing the crime as it happens allows the officer to act decisively and justify the arrest under the law.

While other elements, such as having a warrant in some situations or being a police officer in a position of authority, might play a role in specific cases or jurisdictions, the crux of a lawful arrest often hinges on the clear evidence that a crime has occurred, which is fulfilled by witnessing the event. This direct observation eliminates ambiguity and reinforces the officer's authority to take the suspect into custody.
