核心「后门搜索」漏洞使执法机关在通讯涉及海外非美国人时，透过查询境外资料集中的美国人身分，间接取得美国人的元数据与内容。FBI纪录显示，2023年有超过57,000次这类涉及美国人的查询。改革法案要求在按姓名搜索或查询美国人之前必须先取得搜查令。它同时关闭「数据经纪商」漏洞：虽然通讯提供者不得在无法律程序下直接向政府出售或交付用户资料，但执法机构仍可向从电信与网路公司取得资料的经纪商购买同类纪录。ICE和国土安全部在遣返行动中使用经纪商位置资料，显示这可在美国境内无令状追踪人员。

AI改变了风险分布：不再需要冗长的侦查流程，一次点击就能整合位置与通讯元数据，推断可能的行踪与关系，实现近乎持续式的个人剖析。第702条于2008年在911后架构改革中设立，尽管有三次续约，直到现在仅有有限修正。当政府在国内可针对美国人取用资料的现实已存在，安全需要的辩解便受到削弱。于AI环境下，政府可购买私人可购买资料的论证更难成立，因此文章呼吁立即通过法案并由总统签署，避免政治空间继续收窄。

Rising anxiety over AI-era blanket surveillance has given Congress a narrow window to act before Section 702 of FISA expires next Monday and House leaders may vote as early as Thursday. Republican leadership is pressing for an 18-month renewal that keeps existing powers, and President Donald Trump has publicly backed a clean extension, yet notable GOP resistance remains. A bipartisan Government Surveillance Reform Act is positioned as the alternative, targeting major constitutional vulnerabilities in current surveillance law.

The key backdoor-search loophole lets agencies obtain metadata and content of Americans indirectly when communications involve non-Americans abroad by querying Americans’ identities in foreign datasets. FBI records show more than 57,000 such U.S.-person queries in 2023. The reform bill would require warrants before searching or querying U.S. persons by name. It also closes the data-broker loophole: although providers cannot directly sell or hand over subscriber data to government without legal process, agencies can now buy equivalent records from brokers who obtained them from phone and internet firms. ICE and DHS use of brokered location data in deportation efforts shows how this can track people inside the United States without a warrant.

AI changes the stakes: instead of slow detective work, one click can merge location and communication metadata, infer likely movements and associates, and enable near-continuous profiling. Section 702, created in 2008 after post-9/11 efforts and renewed three times, has only modest updates despite repeated concerns. Security claims for U.S.-person collection inside the U.S. are weakened by that reality. In an AI environment, the argument that government may buy whatever private actors can buy becomes less defensible, so the article urges immediate passage and presidential signature before political room narrows.
