Did he have one at all then?
The short answer is “we don’t know”. There’s a newspaper article quoting unidentified sources saying he obtained one while living in Robbinsdale, which means it would have been issued by the Hennepin County SO, not Ramsey County. However, in what appears to be a legit response to a Tweeted question, the Hennepin County SO says that state law prohibits them from disclosing information regarding carry license holders.
The issue’s pretty meaningless anyway, there’s no such thing as an “okay to reach for a gun when a cop tells you not to move” permit.
