Where Are the Prosecutions?

The Milwaukee branch office of Pedo Papers (USA Today) has a story loosely centered on the shooting of an off-duty cop near Downtown.

Buried at the end of the story is this:

...[Acting Mayor] Johnson and other public officials have taken particular issue with the increased availability of firearms, which, combined with a variety of other factors, has driven much of the city’s violence since 2020.

Wisconsin saw a 61% jump in gun sales from 2019 to 2020, according to Brady United, a national nonprofit that advocates for stricter gun laws. In Milwaukee, many of the guns confiscated by police were obtained through straw purchases, police have said....

Straw purchases are violations of Federal law.  They are also violations of Wisconsin statutes. 

So where are the prosecutions?

The penalty is 3 to 10 years in prison plus fines.
