美国最高法院推翻了联邦对撞火枪托的禁令，撞火枪托是一种可使半自动武器以与机枪相似的速度射击的装置。 The US Supreme Court has overturned the federal ban on bump stocks, devices that allow semi-automatic weapons to fire at speeds similar to machine guns. 投票以 6 比 3 的结果推翻了 2017 年 ATF 禁止使用这些配件的规定，这些配件曾在 2017 年拉斯维加斯大规模枪击事件中使用。 The 6-3 decision struck down the 2017 ATF regulation that banned the accessories, which were used in the 2017 Las Vegas mass shooting. 批评人士认为，这一决定可能会导致更多大规模枪击事件和美国人的生命损失。 Critics argue that the decision could result in further mass shootings and loss of American lives.
