MIT Technology Review与Times of San Diego的联合调查揭露了美国沿美墨边境部署的AI监控塔存在严重系统性缺陷。根据调查，这些监控设施的故障、算法检测失效和边境执法部门的应答不力，导致超过1050人在其监管范围内丧生1。仅在2024年，新墨西哥州一处沿监控塔附近的沙漠地带就有超过18人死亡1。
研究团队分析了近600座监控塔，而美国海关与边境保护局声称目前有800座塔正在运营1。调查发现多项具体问题，包括监控录像仅保留30天后被删除、除非进行内部审查才予保存1，以及边界巡逻队内部系统（BSITS）自2007年运行至2021年间缺乏统一规则1。2017年美国政府问责办公室曾发现该系统存在数据准确性问题，称监控塔协助逮捕数百次，但实际上该州并无这类塔1。美国海关与边境保护局至今未进行过关于监控有效性的审计1。
调查报告提出四项改革建议，包括进行全面审计、改进死亡数据追踪系统、记录监控技术的逮捕效果和调查潜在的监控失效死亡案例1。与此同时，美国政府计划投入10亿美元，到2034年将虚拟围墙规模增加三倍1。
A joint investigation by MIT Technology Review and Times of San Diego has exposed systemic failures in the artificial intelligence monitoring towers deployed by the U.S. government along the U.S.-Mexico border, revealing that over 1,050 people have died within areas under surveillance by these systems 1. The inquiry examined approximately 600 towers, though federal officials report 800 are currently operational 1. The investigation identified multiple critical problems, including equipment malfunctions, algorithmic detection failures, and border patrol agents' failure to respond to alerts 1.
In 2024 alone, more than 18 deaths occurred near monitoring towers in a small desert section of New Mexico 1. The Border Patrol's internal system (BSITS) has operated since 2007, but unified protocols were not established until 2021 1. A 2017 Government Accountability Office report found that recorded data was inaccurate—agents claimed the towers had assisted in hundreds of arrests in one state where no towers actually existed 1. Additionally, surveillance footage is automatically deleted after 30 days unless an internal review is initiated, and U.S. Customs and Border Protection has never conducted an audit evaluating the towers' effectiveness 1.
To address these deficiencies, the investigation recommends four measures: conducting a comprehensive audit of the system, improving death data tracking mechanisms, documenting arrest outcomes attributed to monitoring technology, and investigating potential cases where monitoring failures contributed to deaths 1. Despite these documented failures, the U.S. government plans to invest $1 billion to triple the virtual wall's scale by 2034 1.
