The Memex program will address the need to move beyond a largely manual process of searching for exact text in a centralized index, including overcoming shortcomings such as:
Limited scope and richness of indexed content, which may not include relevant components of the deep web such as temporary pages, pages behind forms, etc.; an impoverished index, which may not include shared content across pages, normalized content, automatic annotations, content aggregation, analysis, etc.
Basic search interfaces, where every session is independent, there is no collaboration or history beyond the search term, and nearly exact text input is required; standard practice for interacting with the majority of web content, which remains one-at-a-time manual queries that return federated lists of results.
Memex would ultimately apply to any public domain content; initially, DARPA said it intends to develop Memex to address a key Defense Department mission: fighting human trafficking. Human trafficking is a factor in many types of military, law enforcement and intelligence investigations and has a significant web presence to attract customers. The use of forums, chats, advertisements, job postings, hidden services, etc., continues to enable a growing industry of modern slavery. An index curated for the counter-trafficking domain, along with configurable interfaces for search and analysis, would enable new opportunities to uncover and defeat trafficking enterprises.
There are four grounds upon which we find that the telephone records program fails to comply with Section 215. First, the telephone records acquired under the program have no connection to any specific FBI investigation at the time of their collection. Second, because the records are collected in bulk - potentially encompassing all telephone calling records across the nation - they cannot be regarded as "relevant" to any FBI investigation as required by the statute without redefining the word relevant in a manner that is circular, unlimited in scope, and out of step with the case law from analogous legal contexts involving the production of records. Third, the program operates by putting telephone companies under an obligation to furnish new calling records on a daily basis as they are generated (instead of turning over records already in their possession) - an approach lacking foundation in the statute and one that is inconsistent with FISA as a whole. Fourth, the statute permits only the FBI to obtain items for use in its investigations; it does not authorize the NSA to collect anything. In addition, we conclude that the program violates the Electronic Communications Privacy Act. That statute prohibits telephone companies from sharing customer records with the government except in response to specific enumerated circumstances, which do not include Section 215 orders. Finally, we do not agree that the program can be considered statutorily authorized because Congress twice delayed the expiration of Section 215 during the operation of the program without amending the statute. The "reenactment doctrine," under which Congress is presumed to have adopted settled administrative or judicial interpretations of a statute, does not trump the plain meaning of a law, and cannot save an administrative or judicial interpretation that contradicts the statute itself. Moreover, the circumstances presented here differ in pivotal ways from any in which the reenact
