It would appear that you have found this officer guilty of murder without a trial. It would also appear that you have decided, without any evidence, that this shooting was not justified. That the Klan does anything is irrelevant to this case, but that it may have taken a side is no more relevant than the family who was not there, but yet condemns the officer.
I don't know what is more despicable, the Klan or people such as yourself, who are ready to condemn without any justification or moral integrity.
It would seem to me that if you were concerned about black men being shot that you would be marching in Chicago, where there is wholesale murder and drug use taking place. Chicago though is not isolated, as the same situation can be found in Detroit and other cities across our nation, Perhaps, you might take a look at the number of police officers that are killed in the line of duty by thugs who have robbed, killed and raped.
