941.20 History History: 1977 c. 173; 1987 a. 399; 1989 a. 131; 1993 a. 94, 486; 1997 a. 248, 249; 1999 a. 32; 2001 a. 109; 2003 a. 97, 190; 2007 a. 11, 27, 130; 2015 a. 197 s. 51; 2017 a. 12; 2023 a. 51.

941.20 Note Judicial Council Note, 1988: The mental element of the offense under sub. (1) (a) is changed from reckless conduct to criminal negligence. See s. 939.25. If the defendant acts recklessly, the conduct is prohibited by s. 941.30. [Bill 191-S]

941.20 Annotation Pointing a firearm is not a lesser included offense of armed robbery, and a defendant can be convicted of both. State v. Smith, 55 Wis. 2d 304, 198 N.W.2d 630 (1972).

941.20 Annotation A jury instruction that shooting “into” a building under sub. (2) (a) occurs when a bullet penetrates the building, however slightly, conformed with common usage of the word and was not improper. State v. Grady, 175 Wis. 2d 553, 499 N.W.2d 285 (Ct. App. 1993).

941.20 Annotation Police officers do not have an absolute right to point their weapons, but privilege may be asserted as an affirmative defense. State v. Trentadue, 180 Wis. 2d 670, 510 N.W.2d 727 (Ct. App. 1993).

941.20 Annotation Although intentionally pointing a firearm at another constitutes a violation of this section, under s. 939.48 (1) a person is privileged to point a gun at another person in self-defense if the person reasonably believes that the threat of force is necessary to prevent or terminate what the person reasonably believes to be an unlawful interference. State v. Watkins, 2002 WI 101, 255 Wis. 2d 265, 647 N.W.2d 244, 00-0064.

941.20 Annotation The defendant’s as-applied challenge to sub. (1) (b) failed. Sub. (1) (b) did not strike at the core right of the 2nd amendment because the defendant did not act in self-defense. Because sub. (1) (b) did not severely burden the defendant’s 2nd amendment right and was substantially related to the important government objective of protecting public safety, it survived intermediate scrutiny as applied to the defendant. State v. Christen, 2021 WI 39, 396 Wis. 2d 705, 958 N.W.2d 746, 19-1767.
