What is the current state of the law on the definition of prosecutorial misconduct?

^3. "[T]he term prosecutorial 'misconduct' is somewhat of a misnomer to the extent that it suggests a prosecutor must act with a culpable state of mind. A more apt description of the transgression is prosecutorial error." (People v. Hill (1998) 17 Cal.4th 800, 823, fn. 1.)
