This is definitely of the "Space Western" flavor. Earthlings (picture them with cowboy hats on space horses) have colonized Mars and have rounded up all them "derned murderous" Martians that look like spiders (picture bugs with war paint and feathers) into reservations. But one man, named "Crazy" John (who sounds mysteriously like a cosmic Tonto) wishes them to be freed. Kind of trite, but a well-told story. (from "The Critical X Minus One" by Jim Fanisher)
