A Virtual 'Line-Up'?

By mid-2012, police use of social-media imagery for suspect identification was an emerging practice without much corresponding case law or policy. Departments were screenshotting suspect photos from Facebook and tagged-image collections, distributing them in BOLOs and internal lookouts, and — in the cases that drew civil-liberties attention — building informal photo arrays from social-media sources for witness identification.

The legal questions the practice raised cut across several distinct doctrines: Fourth Amendment expectation-of-privacy in posted social-media content, suggestiveness-of-procedure due-process questions under Manson v. Brathwaite for any photo array used for witness ID, and evidentiary authentication questions for the social-media-sourced images themselves. None of these had been comprehensively settled by 2012; courts were resolving them case-by-case.

The technological context that compressed the conversation a few years later — facial-recognition deployment, Clearview-AI-style scraped-image databases, automatic license-plate readers integrating with photo-array workflows — wasn't widely operational yet. The 2012 conversation was about a quieter, more manual practice that the next decade's technology would amplify into a far larger civil-liberties question.
