California Penal Code 18720 PC makes it a serious felony offense to possess substances, materials, or component combinations with the intent to manufacture destructive devices or explosives.
In Los Angeles and throughout Southern California, prosecutors and law enforcement agencies treat allegations involving bomb-making materials with extreme severity due to potential public safety hazards.
Legal Definition and Statutory Text
Under California Penal Code 18720 PC:
"Every person who possesses any substance, material, or any combination of materials or substances, with the intent to unlawfully make or manufacture any destructive device or any explosive, is guilty of a felony."
Key Statutory Definitions
-
Destructive Device Materials: Chemical compounds, explosive powders, fuses, detonators, pipe components, or ordinary substances and household items when possessed with the explicit intent to assemble an unlawful explosive device.
-
Intent to Manufacture: The statute's core mental state; prosecutors must prove you intended to use the materials to build or assemble a destructive device. Completion or full assembly of the device is not required.
-
Constructive or Actual Possession: Control over the materials, whether physically on your person, stored in your residence, kept in a vehicle, or located inside a rented storage unit.
What Must Be Proven to Convict Under PC 18720?
To secure a conviction under Penal Code 18720, the prosecution must establish the following legal elements beyond a reasonable doubt:
-
Possession: You knowingly possessed substances, materials, or components commonly utilized to construct destructive devices.
-
Intent: You harbored the specific intent to use those components to manufacture or assemble an explosive or destructive device.
-
Knowledge: You were consciously aware of the presence and nature of the materials in question.
Hypothetical Examples
-
Example 1: Police execute a residential search warrant and uncover metal pipes, end caps, and loose gunpowder stored together, leading to a PC 18720 charge for possessing pipe-bomb components.
-
Example 2: Law enforcement stops a vehicle and discovers commercial chemical compounds alongside handwritten assembly notes for improvised explosives, triggering destructive device material allegations.
-
Example 3: An individual lawfully purchases ordinary household cleaning supplies and hardware components for legitimate home renovation projects, but is falsely accused of possessing bomb-making materials due to a misunderstanding.

Legal Defenses to PC 18720 Charges
An experienced criminal defense attorney can build a robust defense using several established legal strategies:
-
Lack of Intent: Proving that you possessed ordinary materials for legitimate, lawful purposes (such as academic, industrial, commercial, or hobbyist use) rather than bomb-making.
-
Lawful Possession of Common Materials: Many substances identified by police have valid everyday applications; demonstrating innocent context defeats the prosecution's case.
-
Illegal Search and Seizure: If law enforcement officers discovered materials during an unconstitutional traffic stop, warrantless search, or invalid warrant execution, your attorney can file a suppression motion under Penal Code 1538.5.
-
Lack of Knowledge: Establishing that you were entirely unaware of the presence or nature of the materials located on your property.
