Well, actually it’s Dominic Black’s gun, and I believe it’s still a piece of evidence in Binger’s prosecution of Black, so I don’t think Rittenhouse or Black are free to do anything with it at this time.
Yes, that case is still pending, with the next court date January 10, 2022. Binger would love to add a tidbit about evidence destruction. https://wcca.wicourts.gov/caseDetail.html?caseNo=2020CF001275&countyNo=30&index=0&mode=details
