How Does the Prosecutor Prove Assault With a Deadly Weapon?
To prove that you are guilty of “Assault With a Deadly Weapon,” the prosecutor has to prove the following facts or elements1:
- You willfully assaulted another person with or without a deadly weapon2
To be clear, California’s Penal Code Section 245(a)(1) pc, et seq. provides for penalties to anyone who uses a
- A deadly weapon,
- instrument other than a firearm, or
- Who uses “any means of force likely to produce great bodily injury.”3
Force With A Weapon
You did an act with a deadly weapon other than a firearm; a firearm; a semiautomatic firearm; a machine gun; an assault weapon; a .50 BMG rifle that by its nature would directly and probably result in the application of force to a person;4
Examples:
Other than the traditional deadly weapon, such as a gun, a “deadly weapon” can also be any object when used in a way that is likely to result in serious harm to another person, such as:
- Any sharp and/or pointy object, such as a pencil, broken bottle, or a high heel shoe
- Car
- Dog
- Any other object that is used in a way that can cause severe harm to another person
Force Without A Weapon
You did an act with a deadly weapon other than a firearm; a firearm; a semiautomatic firearm; a machine gun; an assault weapon; a .50 BMG rifle that by its nature would directly and probably result in the application of force to a person;4
Examples:
Other than the traditional deadly weapon, such as a gun, a “deadly weapon” can also be any object when used in a way that is likely to result in serious harm to another person, such as:
- Pushing,
- Hitting,
- Punching,
- Kicking
- Scratching
- Choking
- Biting
When you acted, you were aware of facts that would lead a reasonable person to realize that your act by its nature would directly and probably result in the application of force to someone.
When you acted, you had the present ability to apply force likely to produce great bodily injury with a deadly weapon other than a firearm; with a firearm; with a semiautomatic firearm; with a machine gun; with an assault weapon; or with a .50 BMG rifle to a person. 5
Great Bodily Injury
Great bodily injury means significant or substantial physical injury. It is an injury that is greater than minor or moderate harm.

No one needs to actually have been injured by defendant’s act. But if someone was injured, this fact can be used, along with all the other evidence, in deciding whether the defendant committed an assault and if so, what kind of assault it was.
Examples:
Some examples of qualifying “great bodily injury” include the following:
- Any cuts or lacerations that require surgical stitching
- Broken limbs
- Broken/crushed/torn teeth
How Can You Fight Charges Under Penal Code 245(a)(1) pc?
The most common defenses that can be used to defend you from “Assault With a Deadly Weapon” are as follows:
You Were Defending Yourself
If you honestly and reasonably believe that you are going to suffer great bodily injury, or if you honestly and reasonably believe that another person is about to suffer great bodily injury, you are justified in using as much force as is reasonably necessary to repel the force.

In such an instance, self-defense is a valid defense.
Inability To Carry Out That Threat
If when you acted, you had no present ability to carry out the assault, or to apply force likely to produce great bodily injury with a deadly weapon or otherwise, you are not guilty of this offense.
Example:
You threatened to shoot the alleged victim with a gun that you said you have in your pocket, but you in fact did not have a gun. In this case, you have not committed an assault with a deadly weapon, because you did not have the present ability to carry out the assault.
Lack Of Intent
If you accidentally assaulted someone without intending to do so, your conduct does not qualify as an assault with a deadly weapon.
Example:
If you swung a bat intending to hit a baseball, but you accidentally hit the person standing behind you, you did not commit an assault with a deadly weapon, because you did not do so willfully. It was only an accident.
