These are what the case was about. The floppy disk that caught Dennis Rader, and the genealogy database that helped identify Joseph DeAngelo, are tools — extraordinary, consequential, and technically interesting tools, but tools in the service of a purpose that exists independently of the tools themselves. The purpose is accountability for what was done to specific people. The tools helped reach it. The people it was for were there before the tools existed and will live with the results long after the tools are taken for granted.
