What does Penal Code Section 187 define?

Penal Code Section 187 defines murder, which is the unlawful killing of a human being with malice aforethought. This section emphasizes the intentional nature of the act and distinguishes it from other types of homicide that may not involve premeditation or intent to kill, such as manslaughter. It is a critical part of California law that outlines the seriousness of taking another person's life deliberately, and it establishes the foundational legal principles regarding the definition and elements required for a murder charge. Understanding this distinction is essential for law enforcement, as it guides the investigation and prosecution of such cases, focusing on the intent and circumstances surrounding the crime.
