Flock 推出的监控工具已从单纯的车牌辨识大幅扩展，现可让警方透过文字描述与 AI 技术，在各地的摄影机画面中搜寻并追踪特定人员。这项功能引发了严重争议，全美多个警局传出滥用该系统追踪伴侣、前任等非公务目标的跟踪与渎职丑闻，促使部分城市解除合约，并引发国会及民权团体对大规模监控的强烈质疑。

面对外界批评，Flock 推出了包含关键字审查及事后稽核等一系列防护措施，但技术分析与专家指出，这些机制无法有效阻止滥用。审查系统主要针对文字提示词进行评估，对种族或宗教等敏感字词设置限制，但警察可轻易透过服装特征绕过封锁，且对政治与文化表达仅提供警告而非强制阻断，导致防护网多数时候只扮演记录而非拦截的角色。

隐私倡议者与技术专家进一步强调，Flock 的黑箱 AI 决策与有限的输入审查根本无法解决大规模监控带来的结构性风险。虽然该公司宣称正陆续强制实施搜寻原因登记与异常模式警示，但整体系统的监督与法规执行仍高度仰赖地方警局的自律，这使公众隐私持续暴露在无节制搜索与潜在权力滥用的巨大威胁之下。

Flock's surveillance capabilities have expanded significantly beyond basic license plate reading, enabling police officers to search for and track individuals across networked cameras using natural-language descriptions powered by AI. This advanced tracking suite has sparked severe controversy, as dozens of officers nationwide have been implicated in stalking and unauthorized tracking of partners and acquaintances, prompting city councils to cancel contracts and drawing scrutiny from lawmakers and civil liberties organizations.

In response to the mounting criticism, Flock introduced guardrails including automated content moderation and auditing tools, yet technical analysis and experts demonstrate that these measures fail to prevent abusive surveillance. The moderation system relies on server-side filters that restrict terms like race or religion, but officers can easily circumvent them using descriptive proxies like clothing, while politically protected expressions only trigger dismissible warnings rather than absolute blocks, effectively creating an administrative record rather than an active deterrent.

Privacy advocates and AI safety specialists argue that Flock's opaque moderation and input-only filters merely address individual bad actors without resolving the fundamental harms of mass surveillance. Although the company is moving to mandate audit logging and case number requirements, the actual governance and enforcement of these powerful tools remain dependent on local police departments, leaving substantial loopholes for privacy violations and unwarranted fishing expeditions across public spaces.
