Recently, law enforcement agencies across the United States have increasingly used flashbang grenades—also known as stun or distraction devices—to disperse protest crowds, sparking widespread public concern and debate. Flashbangs are non-lethal weapons designed to temporarily incapacitate individuals through an intense burst of light, loud noise, and concussive force. While commonly employed in tactical raids or riot control, their deployment against largely peaceful demonstrators has drawn criticism for excessive force, potentially causing panic, burns, or permanent hearing damage. Human rights organizations argue that de-escalation and dialogue should take precedence over militarized tactics. Supporters, however, contend that flashbangs can effectively restore order and minimize lethal confrontations when situations escalate or pose a threat of violence. Experts urge clearer guidelines on their use and enhanced training for officers to balance public safety with civil liberties. This practice also underscores deeper societal divisions in the U.S. regarding police reform, racial equity, and the right to peaceful assembly.
近日，美国多地在处理抗议活动时，执法人员频繁使用闪光弹（又称震撼弹或眩晕手榴弹）驱散人群，引发公众广泛关注与争议。闪光弹是一种非致命性武器，通过瞬间释放强光、巨响和冲击波，使目标暂时失能，常用于突袭行动或控制骚乱。然而，在面对和平示威者时使用此类装备，被批评者认为过度使用武力，可能造成恐慌、烧伤甚至永久性听力损伤。人权组织指出，执法部门应优先采取对话与缓和策略，而非依赖军事化手段。支持者则辩称，在局势失控或存在暴力风险时，闪光弹可有效恢复秩序并减少致命冲突。专家呼吁制定更明确的使用规范，并加强执法人员培训，以平衡公共安全与公民权利。此现象也反映出美国社会在警务改革、种族平等及集会自由等议题上的深层分歧。
