◇ The terms premeditation malice aforethought deliberate, and willful are often used in statutes either along with or instead of intent to describe the necessary mental state for a crime. In some jurisdictions the premeditation has to occur only moments before the act, while in others it must precede the act by an appreciable amount of time.
