Ms did testify about the gun and said that "There were other reasons for having a gun". He was not questioned further on this by any attorney. I understood it to mean that he claimed to own a gun for his own protection as he was heavy into illegal activities.
I also noticed that Isho was doing DM a favour by giving him the gun at cost and not making a penny. Wondering why a casual acquaintance would go out of his way to do such a favour. IMO DM & Isho were partners in a much bigger scale then anybody has testified to
There was some testimony about the gun that was shut out due to legal arguments wasn't there? MS actually introduced DM to Isho, and MS mentioned contacting Isho again after the murder. So both MS and DM were involved with an illegal gun dealer.
