Wisconsin Statute 948.60 regulates the possession of a dangerous weapon by persons under 18 years old. In paragraph (2) (a) it states:
(a) Any person under 18 years of age who possesses or goes armed with a dangerous weapon is guilty of a Class A misdemeanor.
Paragraph (3) lists exceptions. (3)(c) excludes most people who are under 18, except those in violation of 941.28 or 29.304 and 29.539.
(c) This section applies only to a person under 18 years of age who possesses or is armed with a rifle or a shotgun if the person is in violation of s. 941.28 or is not in compliance with ss. 29.304 and 29.593. This section applies only to an adult who transfers a firearm to a person under 18 years of age if the person under 18 years of age is not in compliance with ss. 29.304 and 29.593 or to an adult who is in violation of s. 941.28.
Statute 948.60 only applies to a person under the age of 18 who are in violation of 941.28 or not in compliance with 29.304 and 29.593.
What does it take to be in violation of 941.28? Here is the statute:
(2) No person may sell or offer to sell, transport, purchase, possess or go armed with a short-barreled shotgun or short-barreled rifle.
In the statute, short-barreled shotguns or short-barreled rifles are those which require a special license under the National Firearms Act. In general, those are rifles with a barrel less than 16 inches in length or shotguns with a barrel less than 18 inches in length, or either which have an overall length of less than 26 inches.
The rifle carried by Kyle Rittenhouse, as an ordinary AR15 type and does not fall into those categories, so Kyle was not violating 941.28.
Was Kyle in violation of Wisconsin statute 29.304 and statute 29.539? These statutes deal with hunting regulation and with people under the age of 16 carrying rifles and shotguns. First, statute 29.304:
29.304 Restrictions on hunting and use of firearms by persons under 16 years of age.
(b) Restrictions on possession or control of a firearm. No person 14 years of age or older but under 16 years of age may have in his or her possession or control any firearm unless he or she:
Kyle is reported to be over 16 years old, so he was not violating statute 29.304.
How about statute 29.539?
29.593 Requirement for certificate of accomplishment to obtain hunting approval.
Kyle was not hunting, so statute 29.539 does not apply.
To sum up: Wisconsin statutes 940.60 only forbid people under the age of 18 from possessing or carrying dangerous weapons in very limited cases. If a person is 16 years of age or older, the statute only applies to rifles and shotguns which are covered under the National Firearms Act as short-barreled rifles or shotguns. People who are hunting have to comply with the hunting regulations, and there are general restrictions for people under the age of 16.
If only folks at Politifact and the rest of the MSM were that good at research and analysis. They can only dream and wish.
