Robber/Gunman

A Robber/Gunman posing as an L.A. Times news reporter supposedly conducting an interview with winners of "illegal numbers lotteries" drops by the Sanford junkyard in the episode of Sanford and Son titled "By the Numbers", which was the first episode of the 2nd season. The role of the fake reporter/robber was played by actor David Moses, who later appears in the episode titled "The Card Sharps" that same season (#2.6).

The Robber and Fred's numbers winnings
Apparently word spreads quickly when someone wins in the in the illegal numbers racket lotteries in the Watts community where Fred and Lamont lives; Not only was Bubba, who supposedly had his car impounded, where he couldn't take Fred, who won $600, but spent $100 on his new outfit, to Las Vegas, and Aunt Ethel, who claimed to need a gall bladder operation, a good portion of his winnings, but a robber who had a Smith and Wesson revolver in his camera/notepad bag, who was posing as a reporter for the Los Angeles Times, pulls a gun on the two, Fred says while being held up "Hey, you're not from The Times!", the robber responds, "If I was, would I be doing this, dummy!?"
