Battery to a law-enforcement officer is one of Wisconsin’s most aggressively charged offenses. Officers and prosecutors treat any contact during an arrest as potential battery-to-LEO, and the felony tier follows automatically. The defense focus is on two questions: did the State actually prove the officer’s status was known, and was the contact within the limited Wisconsin self-defense privilege against excessive force?
This page covers § 940.20(2) specifically. For the broader battery framework, including the § 940.19 tiers, the § 939.22 injury definitions, and the domestic-violence overlay, see the main battery and assault page.
What the State Must Prove
Under § 940.20(2), the State must prove the defendant intentionally caused bodily harm to a law-enforcement officer or firefighter, that the victim was acting in an official capacity, and that the defendant knew the victim’s status. Class H felony: 6 years, $10,000.
The same statute extends to specific other professional victims, each at its own tier:
| Statute | Victim category | Class | Maximum |
|---|---|---|---|
| § 940.20(2) | Law enforcement officer / firefighter | Class H felony | 6 years / $10,000 |
| § 940.20(2m) | Probation, parole, aftercare agent | Class H felony | 6 years / $10,000 |
| § 940.20(2r) | District attorney | Class H felony | 6 years / $10,000 |
| § 940.20(7) | Juror | Class H felony | 6 years / $10,000 |
| § 940.20(3) | Public officer | Class I felony | 3.5 years / $10,000 |
| § 940.20(5) | School district officer / employee | Class I felony | 3.5 years / $10,000 |
| § 940.201 | Witness | Class H felony | 6 years / $10,000 |
The Knowledge Element Is the Whole Defense
The State must prove the defendant knew the victim was an officer (or firefighter, etc.) at the moment of the contact. This is not negligence; it is actual knowledge or strong reason to know.
- Plain-clothes / undercover. An officer not in uniform, in an unmarked vehicle, who did not clearly identify themselves before the contact, has a contestable knowledge case.
- Off-duty officers on personal business. An off-duty officer working as a bouncer, in a personal dispute, or outside the territorial jurisdiction may not be acting “in an official capacity,” which independently defeats the charge.
- Mass-event confusion. Crowd scenes, multi-officer arrests, low-visibility conditions, and rapid-onset encounters all produce real arguments that the defendant could not reasonably have known the victim’s status in time to avoid the contact.
- Initial encounters with detectives or supervisors. Officers in suits, on phone calls, or in transitional moments may not be perceived as acting in their official capacity even when they are.
Self-Defense: Limited, But Real
Wisconsin does not give defendants the right to resist a lawful arrest, even an arrest the defendant believes is wrong. But Wisconsin does preserve a self-defense privilege against unlawful or excessive force, even by an officer, under the general self-defense statute at § 939.48.
The line:
- An officer using force within use-of-force policy, in service of a lawful arrest, is acting lawfully. Resistance is not privileged.
- An officer using force that exceeds policy or that exceeds what a reasonable officer would use under the circumstances opens the door to a self-defense privilege for the defendant.
Excessive-force defenses require careful evidence development:
- Bodycam, dashcam, surveillance footage of the actual force.
- Use-of-force policies for the specific agency.
- Officer training records (force-options, de-escalation).
- Use-of-force expert review.
- Defendant’s medical records documenting the injuries actually sustained.
In cases where the officer’s conduct exceeded the lawful threshold, the defense can defeat both the battery charge and any associated § 946.41 resisting count.
How Battery-to-LEO Charges Actually Get Filed
The most common patterns:
- Arrest-resistance contact. A struggle during arrest where the officer was bumped, struck, kicked, or scratched. Often filed alongside resisting under § 946.41.
- Spitting or throwing fluid. Wisconsin has separately criminalized “throwing or expelling bodily fluid” at officers in some contexts, but the conduct can also be charged as battery to an officer.
- Contact during transport. Defendants in handcuffs who kick at officers, head-butt the cage, or otherwise make contact during transport are routinely charged at the felony tier.
- Booking-incident contact. Any contact with deputies during fingerprinting, holding-cell management, or strip-search procedures.
- Domestic-violence call escalations. Officers respond to a domestic call, the incident escalates, and contact occurs during the attempted detention.
Each pattern has different evidence priorities. The defense almost always starts with the bodycam and the use-of-force documentation.
The Resisting Overlap
Battery to an officer under § 940.20(2) and resisting an officer under § 946.41 are routinely charged together. The conduct overlap is heavy:
- Resisting causing soft-tissue injury, § 946.41(2r), is a Class H felony. Same tier as battery-to-LEO.
- Resisting causing great bodily harm, § 946.41(2t), is a Class G felony. Higher than basic battery-to-LEO.
- The battery charge requires intentional harm; the resisting charge requires only that the defendant caused the harm during resistance.
Defense strategy commonly attacks both. A successful suppression of the underlying stop, a successful self-defense argument, or a successful knowledge-of-status defense often resolves both counts together. See our resisting and obstructing page for the parallel framework.
Defenses We Regularly Raise
- Lack of knowledge of officer status. Plain-clothes, off-duty, undercover, mass-event confusion. Defeats the knowledge element.
- Officer not acting in official capacity. Off-duty personal business, outside territorial jurisdiction, or in a context where the official-capacity test fails.
- Self-defense against excessive force. Limited but real. Requires bodycam, use-of-force policy, and expert review.
- Lack of intent. Contact during a struggle is not always intentional. Reflexive movement, falling, and incidental contact during restraint can all defeat the intent element.
- Lack of bodily harm. The State must prove actual bodily harm under § 939.22(4). Officer reports of “redness” or “soreness” without medical documentation are challengeable.
- Suppression of the underlying stop. A successful Fourth Amendment motion can dismantle the entire prosecution.
- Tier reduction. Plea-down to ordinary § 940.19(1) battery (Class A misdemeanor) preserves federal firearm rights and eliminates most felony-record collateral.
What to Do If You’re Charged
- Get the bodycam, dashcam, and any third-party video. Preservation letters go out within hours of engagement.
- Photograph any injuries you sustained. Bruising, abrasions, or use-of-force marks. ER records if you sought treatment.
- Pull the agency’s use-of-force policy. Public-record request, supplemented by discovery in the case.
- Identify witnesses to the encounter. Bystanders, passengers, family members. Memories degrade quickly.
- Do not give a statement. Anything you said at the scene, in transport, or in booking is already in the report. Do not add to it.
