Now part of the Department of Homeland Security, the Secret Service was created by Abraham Lincoln on April 14, 1865 (the day of Lincoln's assassination) as a division of the Department of the Treasury. Tasked with cracking down on counterfeiting, the role of the Secret Service quickly expanded to include a range of fraud investigations, criminal investigations and, eventually, protection for national leaders. The Secret Service served a major role in early computer crime investigations due to their in-house expertise around financial crime, though other agencies have since taken on many of these responsibilities. The Secret Service played an important role in the founding of EFF. In 1990, the Secret Service conducted a series of raids tracking the distribution of a document illegally copied from a BellSouth computer that described how the emergency 911 system worked, referred to as the E911 document. The Secret Service believed that, if "hackers" knew how to use the telephone lines set aside for receiving emergency phone calls, the lines would become overloaded and people facing true emergencies would be unable to get through. EFF's first client was Steve Jackson Games, a small games book publisher who was wrongfully targeted during one of the E911 raids. Through this case, a court held for the first time that electronic mail deserves at least as much protection as telephone calls. And EFF was officially created, combining Constitutional legal expertise and technical savvy to address the attacks on civil liberties implicated by new technologies.
