You are oh so correct. It is not racial profiling however. It is criminal profiling. On September 11, 2001 nearly 3000 American (and other nationals) were murdered. And a profile of the murders should be created so that future murders of this sort can be prevented.
I think most of the people visiting this web site could probably make a pretty good profile of the perpetrators of this crime.
