Dick Wolf taught us the basics of criminal prosecution long before law professors could shape our malleable minds. "In the criminal justice system, the people are represented by two separate yet equally important groups: the police who investigate crime and the district attorneys who prosecute the offenders."
As it applies to our world now, we view these "two, separate, yet equally important groups" in terms of qualified immunity and prosecutorial immunity.
Frankly, we get so wrapped up in police officers' qualified immunity appeals that we forget about absolute prosecutorial immunity. That changes - at least briefly - today with this Second Circuit Court of Appeals opinion.
