What is considered a crime premeditated?

"A crime is premeditated when it is considered beforehand and deliberate when the decision to commit the crime is formed or arrived at or determined upon as a result of careful thought and weighing of considerations for and against the proposed course of action. [Citations.] [] The process of deliberation and premeditation does not require any extended period of time: ' "The true test is not the duration of time as much as it is the extent of the reflection. Thoughts may follow each other with great rapidity and cold, calculated judgment may be arrived at quickly. . . ." ' [Citations.] The requirement of premeditation and deliberation excludes acts that are the 'result of mere unconsidered or rash impulse hastily executed.' " (People v. Gonzalez (2012) 210 Cal.App.4th 875, 887.)
