California Law
Must be written in a book of law (statutory).
No common law; if not written, no violation.
Legal Concepts
Letter of the Law: Exact wording.
Spirit of the Law: Reason behind the law.
California Code Books: The written laws.
Case Law: Court interpretations.
Constitutional Law: From the U.S. Supreme Court.
Criminal law, both substantive and procedural are found in California state codes and interpreted by courts. This forms the foundation of criminal justice.
Radio Codes & Communication
San Francisco's radio codes may differ from other Bay Area agencies.
Request plain talk from other agencies (e.g., CHP) to avoid misinterpretation (e.g., "212214").
Victim's Role in Prosecution
D.A. often drops cases if the victim doesn't want to prosecute due to heavy backlogs and the victim being the main witness.
Citizens may believe the victim controls prosecution, but this isn't true.
Example: Shopkeeper extortion case: Even if the shopkeeper wants to drop charges, the D.A. can prosecute, subpoena the shopkeeper, and use video evidence.
Definition of a Crime
A crime or public offense is an act committed or omitted in violation of a law forbidding or commanding it.
Punishments upon conviction:
Death
Imprisonment
Fine
Removal from office
Disqualification from holding office.
Simplified: An act violating a law or a failure to act when commanded by law, with punishment upon conviction.
Elements of a Crime
Every crime requires:
Act and intent.
Act and criminal negligence.
Example:
Caller reporting a stolen phone. Determine how it was stolen.
If the phone was lost, it is classified as lost property, report online at sanfranciscopolice.org/reports to save time.
If it was robbery with a bomb, then use the codes 211/221.
Criminal Act
Physical action (e.g., punching).
Failure to act (e.g., not using a seat belt).
Possession of illegal items (e.g., drugs, burglary tools, weapons). No physical action is needed for possession-based offenses.
Criminal Intent
Accused's state of mind during the crime.
Intent (or criminal negligence) must be proven.
Four types of intent:
General
Specific
Transferred
Criminal negligence
Crime vs. Tort
Crime:
Criminal intent.
State is the prosecutor.
Few settlements occur out of court.
Fines go to the public treasury.
Contributory negligence is not a defense.
Purpose is punishment.
Statutory limit to fines.
Tort (Civil Wrong):
No criminal intent (unless also a crime).
Victim is the prosecutor.
Most settlements are out of court.
Damages go to the victim.
Contributory negligence may be a defense.
Purpose is to restore the original condition.
No limit to damages.
Dispatchers are generally not involved in civil disputes.
Distinguish criminal intent/negligence from civil matters.
Example: Roommate breaking glasses: Initially civil, but escalates to a potential police matter if threats/fear are involved.
General Intent
Presumed intent based on the situation.
Example: Herbert throws a rock through Sam's window after an argument.
Priority call if the suspect is on scene. Justify the priority in the text.
If the suspect leaves, get the direction of travel.
Abbreviations & Descriptions
Know the acceptable CAD abbreviations.
Suspect description order: Race, gender, age, height, build, clothing (top to bottom), any weapon seen.
Vehicle description order: Color, year, make, model, body, license plate (acronym: CYMBL).
Specific Intent
Requires a particular state of mind, written into the statute.
Recognized by phrases like "with the intent to."
Transferred Intent
Intent can be transferred from one object/person to another.
Example: shoots at with intent to kill, But Mrs. and shoots and kills C
Criminal Negligence
Failure to exercise ordinary prudence.
Example: Drunk driving resulting in death. The death is a consequence of criminal negligence, which equates to intent.
Elements of a Crime & Burden of Proof
Elements of each crime are in the penal code.
To have a homicide, person must be deceased, and somebody's criminality must be the source of the loss. Example, injury or loss must be present
In the U.S., individuals are innocent until proven guilty.
The state must prove:
A crime was committed.
The defendant committed it.
