Arrested with a Weapon During Another Crime? Here’s What You’re Facing in California — And How Perlman & Cohen Can Help

Last Modified: May 16, 2025

California takes weapon-related offenses seriously—and when a firearm or other weapon is involved in the commission of another crime, the legal consequences escalate quickly. Whether you’re charged with robbery, drug possession, assault, or burglary, the presence of a weapon can lead to sentence enhancements, felony charges, and long-term penalties that go far beyond the base offense.

At Perlman & Cohen, we’ve represented countless clients in Los Angeles who were charged not only with a primary crime, but also faced enhanced penalties for being armed or using a weapon. In many cases, we’ve been able to get these enhancements dropped or reduced, helping our clients avoid years of additional prison time.

In this article, we explain how California handles weapon enhancements, the laws that govern these cases, and what defense strategies can be used to fight the charges—or reduce the penalties.

What Is a Weapon Sentence Enhancement in California?

A sentence enhancement is an added penalty on top of the punishment for the underlying crime. In weapon-related cases, enhancements often apply if the defendant:

  • Was armed with a weapon
  • Used a weapon during the commission of a felony
  • Intentionally discharged a firearm
  • Caused great bodily injury or death using a weapon

These enhancements are applied under California Penal Code § 12022–12022.53, depending on the specific facts of the case.

Importantly, a weapon enhancement is not a separate charge—it’s an additional punishment the prosecution seeks if they can prove a weapon was involved.

Penal Code § 12022: Being Armed with a Weapon During a Felony

This enhancement applies when a person is armed with a weapon during the commission or attempted commission of certain felonies—even if the weapon wasn’t used.

Examples include:

  • Carrying a weapon while committing burglary
  • Being armed during drug trafficking or manufacturing
  • Having a weapon during a robbery, even if not brandished

Punishment:
An additional 1 to 5 years in state prison, depending on the offense and whether the weapon was personally used or just present.

Penal Code § 12022.5: Using a Weapon During a Felony

This applies when a weapon is actually used in the commission of a felony. “Use” means the weapon was displayed, fired, or used to intimidate a victim.

Punishment:
An additional 3, 4, or 10 years in prison. This applies to felonies like assault with a deadly weapon, carjacking, and domestic violence.

Penal Code § 12022.53: “10-20-Life” Law

Known as the “10-20-Life” law, this enhancement dramatically increases prison time when a weapon is used during serious felonies, including:

  • Murder
  • Robbery
  • Rape
  • Kidnapping
  • Carjacking

Punishment:

  • 10 years: If the weapon was used (e.g., shown, pointed, or brandished)
  • 20 years: If the weapon was fired
  • 25 years to life: If someone was injured or killed as a result

These enhancements are mandatory if proven—meaning judges cannot reduce or eliminate them unless the prosecution agrees or specific legal challenges are raised.

What Counts as “Using” a Weapon in These Cases?

Prosecutors do not have to show that the weapon was fired. Under California law, "use" of a weapon can mean:

  • Brandishing the weapon
  • Pointing it at someone
  • Threatening with the weapon in hand
  • Using the weapon as a show of force

Even if the weapon was not loaded—or never discharged—these facts may still trigger a severe enhancement.

What If the Weapon Belonged to Someone Else?

You can still face enhancement charges even if:

  • The weapon belonged to another person
  • The weapon was never used but was present in the car or location
  • You were unaware of the weapon’s presence (in certain constructive possession cases)

However, your level of knowledge and control over the weapon can be critical in building your defense.

Federal Charges for Weapon Use During Crimes

Federal law also contains weapon enhancements under 18 U.S. Code § 924(c), particularly for cases involving:

  • Interstate drug trafficking
  • Bank robbery
  • Federal fraud schemes
  • Organized crime (RICO)

Federal weapon enhancements can include mandatory minimums of 5 to 25 years, and sentences must be served consecutively to any base sentence.

Real-World Example: How a Weapon Enhancement Changes a Case

Base charge: Robbery
Standard penalty: 2–5 years in state prison

With enhancement:

  • +10 years for using a weapon under PC § 12022.53(b)
  • Total sentence: 12–15 years

This enhancement can double or triple the sentence—and makes the person ineligible for probation or early release programs.

How Perlman & Cohen Defends Against Weapon Enhancements

Our defense approach is tailored to the specific facts of each case. We analyze every detail, including how the weapon was discovered, who had control, and whether the enhancement applies as a matter of law.

1. Challenging the Underlying Felony

If we can weaken or dismiss the underlying felony charge, the enhancement automatically falls away.

2. Disputing “Use” or “Armed” Allegations

We argue that the weapon was not used or under your control. Was it visible? Loaded? Carried by someone else? These details matter.

3. Illegal Search or Seizure

If the weapon was found during an unconstitutional search, we may file a motion to suppress under the Fourth Amendment, removing the weapon from evidence entirely.

4. Romero Motion (Dismiss Enhancement)

Under People v. Romero, courts have discretion to strike certain enhancements in the interest of justice. We file Romero motions when appropriate to reduce sentencing exposure.

5. Negotiated Plea Agreements

If dismissal isn’t possible, we work with prosecutors to negotiate removal of the enhancement in exchange for a plea on the base offense, significantly reducing potential prison time.

What to Do If You’re Charged with a Weapon Enhancement

Do not assume the court will show leniency just because the weapon wasn’t fired or no one was injured. These enhancements are often applied aggressively, and the penalties are severe—even for first-time offenders.

If you're facing charges for a crime involving a weapon:

  • Do not speak to police without an attorney present
  • Do not try to explain or justify the presence of the weapon
  • Preserve any evidence or communications that support your defense
  • Contact an experienced criminal defense lawyer immediately
