Goes back even further to the time of Streets of SF which had many references to the “danger” of evil handguns. Another somewhat anti gun show earlier was the original Hawaii 5-0.
Streets Of San Francisco did pick on handguns a few times.
It is still a very good series.
Letters From The Grave, 45 Minutes From Home, 24 Karat Plague, Deathwatch, Inferno, Most Deadly Species, Judgement Day are among my favorites.
Hawaii 5-0
With Hawaii 5 0 you knew as soon as a soldier or Viet Nam Vet showed up they were the psycho bad guy
