When can a peace officer arrest someone without a warrant?

A peace officer can arrest someone without a warrant when the offense is committed in their presence or view. This principle is grounded in the necessity for immediate action to prevent further criminal conduct or potential harm. When an officer witnesses a crime happening, they have the authority to act swiftly to apprehend the suspect and ensure public safety.

In contrast to other options, simply being requested by a citizen does not grant an officer the authority to arrest without a warrant. Additionally, while some felonies allow for warrantless arrest, it is not limited to felonies alone; it applies to misdemeanors as well, as long as they are observed during the commission of the act. The key point is that the arresting officer must witness the offense occurring to justify a warrantless arrest.
