What does the California Penal Code define as a breach of peace?

The California Penal Code specifically defines "breach of peace" primarily through the context of "disturbing the peace." This is encapsulated in Penal Code Section 415, which outlines behaviors that can disrupt the peace and quiet of a community, such as fighting, making loud noises that might incite disturbance, or using offensive language. These actions are directly associated with causing disruption in public or private areas and threaten the tranquility society seeks.

In contrast, while resisting arrest, criminal mischief, and public disorder may involve behaviors that can contribute to a breach of peace, they are not specifically defined by the Penal Code as such. Resisting arrest focuses on obstructing law enforcement, criminal mischief refers to damaging property, and public disorder encompasses a broader range of conduct that can include a variety of legal infractions. Therefore, "disturbing the peace" is the precise term used in the California Penal Code to describe the breach of peace, making it the correct answer.
