CA §198.

State: California

 

California Penal Code 

Title 8.  Of Crimes Against the Person

Chapter 1.  Homicide

§198. 

A bare fear of the commission of any of the offenses mentioned in subdivisions 2 and 3 of Section 197, to prevent which homicide may be lawfully committed, is not sufficient to justify it. But the circumstances must be sufficient to excite the fears of a reasonable person, and the party killing must have acted under the influence of such fears alone.
