[ ... ]
(2) Except as provided in sub. (4), an actor is immune from civil liability arising out of his or her use of force that is intended or likely to cause death or great bodily harm if the actor reasonably believed that the force was necessary to prevent imminent death or bodily harm to
himself or herself or to another person and either of the following applies:
(a) The person against whom the force was used was in the process of unlawfully and forcibly entering the actor’s dwelling, motor vehicle, or place of business, the actor was on his or her property or present in the dwelling, motor vehicle, or place of business, and the actor knew
or had reason to believe that an unlawful and forcible entry was occurring.
(b) The person against whom the force was used was in the actor’s dwelling, motor vehicle, or place of business after unlawfully and forcibly entering it, the actor was present in the dwelling, motor vehicle, or place of business, and the actor knew or had reason to believe that
the person had unlawfully and forcibly entered the dwelling, motor vehicle, or place of business.
(3) If sub. (2) (a) or (b) applies, the finder of fact may not consider whether the actor had an opportunity to flee or retreat before he or she used force and the actor is presumed to have reasonably believed that the force was necessary to prevent imminent death or bodily harm to
himself or herself or to another person.
(4) The presumption described in sub. (3) does not apply if any of the following are true:
(a) The actor was engaged in a criminal activity or was using his or her dwelling, motor vehicle, or place of business to further a criminal activity at the time he or she used the force described in sub. (2).
(b) The person against whom the force was used was a public safety worker, as defined in s. 941.375 (1) (b), who entered or attempted to enter the actor’s dwelling, motor vehicle, or place of business in the performance of his or her official duties. This paragraph applies only if
at least one of the following applies:
1. The public safety worker identified himself or herself to the actor before the force described in sub. (2) was used by the actor.
2. The actor knew or reasonably should have known that the person entering or attempting to enter his or her dwelling, motor vehicle, or place of business was a public safety worker.
(5) In any civil action, if a court finds that a person is immune from civil liability under sub. (2), the court shall award the person reasonable attorney fees, costs, compensation for loss of income, and other costs of the litigation reasonably incurred by the person.
(6) Nothing in this section may be construed to limit or impair any defense to civil or criminal liability otherwise available.
