akuperma,
For example, the largest shooting incident in America (involving civilians being shot, and not part of a war) would not have been possible without gun control (several hundred recently disarmed civilians murdered at “Wounded Knee” just over a century ago – if they had guns the casulties would probably have been less).
Not to minimize the atrocity of Wounded Knee, but the shooting started during the disarming, not afterward, and between the Lakota and friendly fire, 25 soldiers died, and more were wounded. The Lakota were outnumbered and outgunned, so even if none had been disarmed and shooting started, their death toll probably wouldn’t have changed much – but the army’s death toll would have been higher.
