Under California Penal Code 148.1 PC, making a false bomb threat or reporting a fake explosive device is a severe criminal offense. California law prohibits reporting that a bomb or explosive has been placed—or will be placed—in any public or private location when the individual knows the report is false.
Because false reports trigger mass emergency responses, disrupt public infrastructure, and divert crucial law enforcement resources, prosecutors aggressively pursue PC 148.1 charges as wobbler offenses that can be filed as either misdemeanors or felonies.
What Is California Penal Code 148.1 PC?
Penal Code 148.1 PC makes it illegal to report, convey, or send a false report of a bomb or explosive device to any individual, law enforcement agency, media outlet, or transportation facility, knowing the report is false.
Elements of the Crime
To secure a conviction under PC 148.1, the prosecution must prove the following legal elements beyond a reasonable doubt:
-
False Report: The defendant reported or caused a report to be made that a bomb or other explosive device had been placed or would be placed in a public or private location.
-
Knowledge of Falsity: The defendant knew the report was false when they made it.
-
Intent to Cause Fear (Where Applicable): The defendant made the report directly to another individual with the specific intent to frighten, intimidate, or cause fear of danger.
How False Reports Are Communicated
Under PC 148.1, false bomb threats can be communicated through any medium, including:
-
In-person verbal statements or shouting in public spaces (e.g., airports, transit hubs, school campuses).
-
Phone calls, text messages, or anonymous hotline reports.
-
Emails, social media posts, or digital messaging platforms.
-
Written notes, mail, or placed hoax devices ("fake bombs").
Why False Bomb Threats Are Prosecuted Aggressively
While legitimate public reporting of suspicious packages is encouraged to maintain safety, false reports create catastrophic public safety hazards:
-
Resource Diversion: Emergency responders, bomb squads, and law enforcement officers are pulled away from genuine emergencies and active criminal investigations.
-
Mass Panic and Evacuations: False threats at high-density locations—such as airports, courthouses, or schools—cause chaotic stampedes, pedestrian injuries, and transit shutdowns.
-
Economic Costs: Evacuating commercial buildings, canceling flights, or shutting down public transit systems causes hundreds of thousands of dollars in economic disruption.
Penalties for Falsely Reporting a Bomb Threat in California
In California, a false bomb threat under PC 148.1 is a wobbler offense, meaning prosecutors can charge it as either a misdemeanor or a felony based on the defendant's criminal history and the severity of the disruption.
|
Charge Level |
Incarceration + Fine |
Probation & Court Terms |
| Misdemeanor PC 148.1 | Up to 1 Year in County Jail. Up to $1,000 | Summary probation, community service, court-ordered counseling |
| Felony PC 148.1 | 16 Months, 2 Years, or 3 Years in State Prison. Up to $10,000 | Formal felony probation, mandatory restitution for emergency response costs |
Additional Collateral Consequences
-
Restitution Costs: Courts often order convicted individuals to pay full restitution to law enforcement and emergency response agencies for deployment and bomb squad mobilization costs.
-
Restraining Orders: If the threat was targeted at a specific person, workplace, or group with malicious intent, the court may issue a protective restraining order requiring the defendant to maintain distance.
-
Firearm and Employment Restrictions: A felony conviction results in a lifetime ban on owning or possessing firearms in California and creates significant barriers to background checks for employment and professional licensing.
Legal Defenses Against PC 148.1 Charges
A charge of making a false bomb threat can be successfully defended using several key legal strategies:
-
Good Faith Belief / Lack of Knowledge: If you genuinely believed a bomb or explosive threat was real at the time you made the report, you cannot be convicted under PC 148.1. The law requires actual knowledge that the report was false.
-
Lack of Intent to Cause Fear: When charged under provisions requiring intent to frighten another person, prosecutors must present concrete evidence of that intent. If the statement was a misunderstood joke, sarcasm, or lacked intentional malice, criminal intent is missing.
-
False Accusation or Mistaken Identity: Electronic threats, prank calls, and digital messages are frequently spoofed or made using stolen IP addresses and accounts. Defense attorneys can challenge forensic electronic evidence to prove mistaken identity.
-
Unlawful Search and Seizure: If law enforcement obtained electronic records, phone logs, or physical evidence without a valid search warrant or probable cause, defense counsel can file a Motion to Suppress Evidence under PC 1538.5.
Frequently Asked Questions About California Bomb Threat Laws
Can you be arrested for reporting a bomb threat if you were wrong about a suspicious package?
No. If you see a suspicious package or activity and report it to the police in good faith, you cannot be convicted under PC 148.1—even if the package turns out to be harmless. The prosecution must prove you knew the report was false when you made it.
Is a false bomb threat always charged as a felony in California?
No. PC 148.1 is a "wobbler" offense. First-time offenders or cases involving minimal public disruption are often charged as misdemeanors. However, threats targeting schools, airports, government buildings, or those causing mass panic are typically filed as felonies.
What is the difference between a false bomb threat and a hoax device?
Under California Penal Code 148.1(d) PC, placing or sending a "hoax bomb"—an object designed to look like an explosive device with the intent to cause fear—is treated under the same statutory framework and carries identical misdemeanor or felony penalties.
Can you be ordered to pay for police response costs if convicted?
Yes. Under California law, courts routinely order individuals convicted of falsely reporting a bomb threat to pay restitution to emergency services, police departments, and fire departments to cover the financial cost of their emergency response.
How does a false bomb threat differ from criminal threats under PC 422?
Penal Code 148.1 specifically targets false reports regarding explosive devices. Penal Code 422 PC (Criminal Threats) applies more broadly to any threat of death or great bodily injury directed at a specific individual that causes sustained fear, regardless of whether explosives are mentioned.
