Cal. Pen. Code § 25115
If a person who allegedly violated Section 25100 is the parent or guardian of a child who is injured or who dies as the result of an accidental shooting, the district attorney shall consider, among other factors, the impact of the injury or death on the person alleged to have violated Section 25100 when deciding whether to prosecute the alleged violation. It is the Legislature's intent that a parent or guardian of a child who is injured or who dies as the result of an accidental shooting shall be prosecuted only in those instances in which the parent or guardian behaved in a grossly negligent manner or where similarly egregious circumstances exist. This section shall not otherwise restrict, in any manner, the factors that a district attorney may consider when deciding whether to prosecute an alleged violation of Section 25100.
