The media initially reported a 38-caliber pistol. The media never waits for the Police reports.

Chinese groups like the Chinese Historical Society cited Julius Kahn pushing for the Chinese Exclusion Act to become permanent in 1902, which barred Chinese laborers from entering the United States, as their chief motivation to rename the playground. The act was finally repealed in 1943. In 2018 the Playground was renamed Presidio Wall Playground.

No arrest nor conviction of a scapegoat was ever made for the five media so-called Zodiac murders.
