This is exactly wrong. Profiling does not increase safety whatsoever. Bruce Schneier argues it much better than I would:
> If the choice is between random searching and profiling, then random searching is a more effective security countermeasure. But Dunn is correct above when he says that there are some enormous trade-offs in liberty. And I don't think we're getting very much security in return.
