The Electronic Frontier Foundation is accusing the DEA of improperly withholding documents in a court case that hopes to reveal details about the government s controversial surveillance program known as Hemisphere. The program allows law enforcement to search trillions of AT&T phone records without a warrant as part of investigations. The DEA is refusing to turn over documents that have been withheld or have been highly redacted. The EFF also said it has uncovered new documents that it claims illustrate a cavalier attitude by law enforcement over warrantless searches of trillions of phone records.
