What is the right of arrest for assault?

The correct answer encompasses the nuances of arrest rights in cases of assault. When it comes to the right of arrest, law enforcement officers have the authority to arrest individuals for felony assault without a warrant, as this is a serious crime. For misdemeanor assaults, the situation can differ; an officer may arrest a suspect without having witnessed the incident if they receive a complaint from a victim or witness, thereby allowing for immediate action based on probable cause.

Arrests for misdemeanor offenses typically require additional considerations; they may not occur unless there's a compelling reason or a warrant if the officer did not directly witness the event. Therefore, the dual conditions outlined in the correct choice reflect the legal standards: warrantless arrests for felony assaults and the option for a complaint-based arrest in instances where the officer did not witness the act. This demonstrates a comprehensive understanding of the law regarding arrests for assault, acknowledging both the severity of felony assaults and the procedural avenues available for dealing with misdemeanors.
