Flock Safety 是一间提供自动车牌辨识摄影机的监控公司，其庞大的资料共享网路已在全美各地迅速扩张。以乔治亚州阿尔法勒特市为例，该市的警察部门与全国超过两千个机构共享车牌监控数据，其中甚至包含与警务无关的联邦机构和大学校警。这种错综复杂的跨州资料交换，形成了一个巨大且难以监督的私人监控网。

许多警察单位在不知情的情况下，被系统预设开启了全国查询功能，导致警员能够无限制地存取跨州监控资料。例如俄亥俄州与加州的部分警局直到近期才发现此功能被启用，这不仅违反了某些州对于资料分享的法律限制，也引发了严重的隐私争议，甚至有警员因滥用该系统而被迫辞职。

为应对外界对于隐私外泄与滥用权力的强烈抨击，Flock 公司近期宣布了多项系统更新，包含建议缩短资料保留期限至七天，并强制启用自动稽核工具来侦测异常查询行为。然而，各州对于监控资料的规范落差极大，且警员仍能自由决定查询范围，这使得如何有效约束庞大的监控网路仍是一大挑战。（关键数字： seven days）

Flock Safety is a surveillance company providing automated license plate reader cameras, and its extensive data-sharing network has rapidly expanded across the United States. Taking Alpharetta, Georgia as an example, its police department shares and receives surveillance data with over two thousand entities nationwide, including federal agencies and university police that are unrelated to local law enforcement. This complex, cross-state data exchange has created a massive and loosely regulated private surveillance network.

Many police departments had the nationwide lookup tool enabled by default without their knowledge, allowing officers unrestricted access to cross-state surveillance data. For instance, some police departments in Ohio and California only recently discovered this feature was active, which not only violated certain state laws regarding data sharing but also sparked severe privacy controversies, even leading to officer resignations due to system misuse.

In response to strong public backlash regarding privacy breaches and power abuse, Flock recently announced several system updates, including a recommended reduction of the data retention period to seven days and the mandatory use of an audit tool to detect abnormal queries. However, with drastic differences in surveillance regulations across states and officers still able to freely determine their search scope, effectively restraining this massive surveillance network remains a significant challenge.
