2009 California Penal Code - Section 30-33 :: Title 2. Of Parties To Crime

30.  The parties to crimes are classified as:
   1. Principals; and,
   2. Accessories.

31.  All persons concerned in the commission of a crime, whether it
be felony or misdemeanor, and whether they directly commit the act
constituting the offense, or aid and abet in its commission, or, not
being present, have advised and encouraged its commission, and all
persons counseling, advising, or encouraging children under the age
of fourteen years, or persons who are mentally incapacitated, to
commit any crime, or who, by fraud, contrivance, or force, occasion
the drunkenness of another for the purpose of causing him to commit
any crime, or who, by threats, menaces, command, or coercion, compel
another to commit any crime, are principals in any crime so
committed.

32.  Every person who, after a felony has been committed, harbors,
conceals or aids a principal in such felony, with the intent that
said principal may avoid or escape from arrest, trial, conviction or
punishment, having knowledge that said principal has committed such
felony or has been charged with such felony or convicted thereof, is
an accessory to such felony.

33.  Except in cases where a different punishment is prescribed, an
accessory is punishable by a fine not exceeding five thousand dollars
($5,000), or by imprisonment in the state prison, or in a county
jail not exceeding one year, or by both such fine and imprisonment.
