18. Much Is Speculation Based On Various Tidbits

The FBI has operational responsibility and that is why Graham went to them and why DHS did not take action. With the volume of data they process I can understand why they might move all but the file key data to an inactive file that then gets put back on the active file when they have a ping. Even then you have to eventually purge data -- would 2 years be a reasonable cutoff? Until they can rework their databases DHS should alert the agencies when the system detects data errors like misspellings. Without knowing the volume of data it is hard to determine the best database design. Perhaps the volume is a mismatch for the original estimates so decisions were made to keep the system from crashing on volume, which is necessary short term, but it should not replace a redesign capable of handling the volume.
