This says it all...
Even listening to Moose, one can hear that this is exactly what is happening. Moose said we are working on a physical profile and will release one to you, by the close of business today! (over a week ago)
A day or two later he trotted out a Geographical Profiler and said that the best minds in criminology agree with me (Moose), and that is why we will not be releasing partial profile information (because it paints groups...)
If the profile pointed towards a white American, it would be released immediately. The lack of release is a clue as to the ethnicity of the sniper.
