It's beyond clear that racial profiling would be a good thing—if it worked!

An important heuristic tool

Would that it did, because then everyone could sleep easier knowing that a significant bulwark (not, perhaps, an unfordable earthwork, but an extra battlement) had been erected between us and the enemy. However, race study, or Rassenkunde, is still very much in its infancy. It's doubtful that many people could name more than five of the thirty-three distinguishing features of Mon-Khmer heritage, or could correctly pick out an Octaroon from a crowd of evening revelers. We have already seen how the SAS team in London faced something of a poser: no time to check skull length against jaw occlusion.

No, racial profiling, albeit an important heuristic tool in the Swiss Army knife of democracy, is best left to the experts.
