Fourth Amendment: Digital Warrants and Data-Broker Surveillance

Location data is no longer ordinary business-record doctrine

For years, government argued that data held by third parties lost Fourth Amendment protection. That logic became untenable as phones created persistent records of where people sleep, work, worship, seek medical care, attend protests, and meet other people. Carpenter recognized that comprehensive location data is different. Chatrie extends that reality to geofence acquisition from Google Location History.

The platform should be precise. Chatrie does not mean every geofence warrant is invalid. It means obtaining that kind of location data is a search. The next questions are warrant, probable cause, particularity, minimization, and remedy. Congress should answer those questions rather than leaving them to years of fragmented litigation.

Data brokers are the warrant loophole

If government cannot demand sensitive location data without legal process, it should not be able to buy the same data from a broker with appropriated funds. Commercially available information can reveal clinic visits, worship, protests, military activity, immigration patterns, intimate relationships, and political activity. ODNI's own commercially available information framework recognizes the sensitivity of this data while maintaining that intelligence elements use it under policy controls.

Policy controls are not enough. The rule should track the data and the government use. If the same data would require a warrant, court order, subpoena, or FISA process when compelled, the government should not evade that standard by purchase, license, grant condition, or contract.

Section 702 needs the warrant line restored

Section 702 was designed to target non-US persons abroad for foreign intelligence. That is different from using already-collected 702 data to search for US-person communications. As of July 5, 2026, the statutory authority has lapsed, while public analyses report that existing certifications and directives may continue into 2027. Congress should not use that window for a clean restart.

The Innovation Party should support foreign-intelligence capability against foreign targets, but not warrantless backdoor searches for Americans. Any restoration should require a warrant, FISA order, or warrant-equivalent judicial approval for US-person queries intended to find communications content, with emergency exceptions and later review. Audits, public statistics, and suppression rules should make the line enforceable.

Digital warrants need particularity by design

Digital searches can be broader than physical searches because the dataset itself can be larger than any filing cabinet. A geofence can start with everyone near a location. A device search can expose years of messages, photos, location history, health data, and browsing. A reverse-keyword request can identify people by what they searched before government had a suspect.

Modern warrants should therefore include query limits, time limits, minimization rules, staged disclosure, deletion of nonresponsive data, audit logs, delayed notice where safe, and suppression remedies when officers overrun the authorization. Particularity has to be built into the workflow, not appended as a paragraph.
