I have seen many press reports asserting he had a concealed carry permit, but haven’t seen any authoritative source quoted on that.
Permit or not, a citizen displaying a gun during a traffic stop is stupid, at best, but more likely trying to get shot or shoot someone.
It’s always “source”, no name, or office.
With his mile long rap sheet of felonies and prison time it is impossible he could have had a carry permit. In point of fact he was in violation of his parole by having a gun in his possession.
