The discussion centers around the tragic incident where a four-year-old boy was killed by a falling bullet during a New Year's Eve mass in Atlanta, highlighting the dangers of celebratory gunfire. Participants express outrage over the irresponsible act of firing guns into populated areas, emphasizing that bullets can cause fatal injuries even when falling from a height. The conversation delves into the physics of bullets, discussing terminal velocity and the potential lethality of bullets fired at angles versus straight up. Some participants reference a Mythbusters episode, which concluded that bullets fired straight up are not lethal due to tumbling, while acknowledging that bullets fired at angles can retain significant velocity and pose a danger. The thread underscores the need for awareness regarding the consequences of celebratory gunfire, with statistics indicating that such incidents are not uncommon, particularly in regions where this practice is prevalent. The overarching sentiment is a call for accountability and a reminder of the serious risks associated with negligent gun use.
