第二修正案所說的“Arms”,和今天的槍根本就不是一回事。那個時候就是子彈都沒有工業化。

On October 1, 2017, Stephen Paddock, a 64-year-old man from Mesquite, Nevada, opened fire on the crowd attending the Route 91 Harvest music festival on the Las Vegas Strip in Nevada. From his 32nd-floor suites in the Mandalay Bay hotel, he fired more than 1,000 bullets, killing 60 people^[a] and wounding 411 with the ensuing panic bringing the number of injured to 867. About an hour later, Paddock was found dead in his room from a self-inflicted gunshot wound. His motive is officially undetermined.

The incident is the deadliest mass shooting committed by an individual in United States history. It focused attention on firearms laws in the U.S., particularly with regard to bump stocks, which Paddock used to fire shots in rapid succession, at a rate similar to that of automatic firearms.^[4] Bump stocks were banned by the U.S. Justice Department in December 2018.^[5]
