I wonder how it is legal for a bank to view data obtained by monitoring the Internet on the scale that only the NSA would be able:

  A Palantir user at a bank can, in seconds, see connections between a Nigerian
  Internet protocol address, a proxy server somewhere within the U.S. and
  payments flowing out from a hijacked home equity line of credit, just as
  military customers piece together fingerprints on artillery shell fragments,
  location data, anonymous tips and social media to track down Afghani
  bombmakers.
