The lead cop and the judge who signed off on the late night no knock should be looked into for race discrepancy. What would it hurt to do that? It could be ruled out if that is not the case.
I don't even know if the judge knew the race.
The appropriateness of the warrant and the actions taken should be judged and prosecuted independent of the racial mixture.
Reactions may be influenced by an individual's feelings toward a differing race, but that does not necessarily indicate a crime is a hate crime.
