Flock 运营着覆盖美国数千个社区的车牌识别摄像头网络，执法机构可借此追踪车辆行踪。近期曝光的案例显示，部分警员利用该系统监视前任伴侣或其他人际关系对象，引发公众对监控滥用的担忧。作为回应，Flock 表示将锁定涉及此类行为的警员账号，并加强使用审计。然而，隐私与执法监督领域的专家在接受 Ars Technica 采访时指出，这一措施远不足以解决问题。
专家认为，核心障碍在于执法机构自身缺乏透明度和问责意愿。即便 Flock 在系统层面封禁个别账号，雇佣这些警员的警察局仍可隐瞒内部调查结果，或通过同事账号继续获取数据。换言之，技术公司能限制单个用户的访问权限，却无法强制执法机构公开滥用记录或对涉事警员进行实质惩戒。原文未提供 Flock 具体封禁流程的细节，也未说明各地方警局是否承诺配合披露相关信息。
这一争议发生在更广泛的政府监控讨论背景之下。近期有报道揭露美国政府对左翼及反 ICE 抗议者实施大规模监视（Hacker News 转引《卫报》报道），而民间也出现了反向监督的尝试，例如 SparrowMap 项目通过摄像头记录政府车辆行踪（SparrowMap）。这些动态共同反映出，围绕公共空间监控的权责边界正变得愈发紧张：当监控工具被执法者用于私人目的时，技术供应商的自我约束能否替代制度性监督，仍是一个悬而未决的问题。

On Thursday, Flock announced plans to require all agencies with access to license plate reader data to use a safety tool that automatically detects abnormal activity and locks out cops who abuse their access to stalk people they know in their personal lives.
Flock’s audit assistance tool suspends access when user activity “meets defined criteria for abnormal behavior,” Flock said. The suspension can only be lifted by administrator review, with the goal being “to intervene before misuse becomes recurring or widespread.”
The tech has been available as an optional free feature since April, but only a third of agencies had opted in, Flock said. However, after a single Georgia sheriff’s office used the tool and subsequently arrested three cops who were separately using Flock cameras to stalk acquaintances, Flock CEO Garrett Langley told The Verge that dozens of incidents like these helped his company realize they made a mistake and had to act to correct it.
