I find the credibility of the video suffers greatly, when this so called, "black professor," makes the unsubstantiated claim, that Kenneth Walker never fired first.
It is pretty well known, that, indeed, he was, a) a legal gun owner, b) a drug trafficker
This would speak to his paranoia as to why intruders might be illegally attempting to entering his girlfriend's apartment.
I do find it suspicious, that the police make a claim that they "knocked," on a "no knock," warrant, but I agree with the AG, it more than likely should not have been issued at the home of an "innocent," by standard, however innocent she may or may not have been.
The guy in the video claims neighbors state the police never announced they were police before entering. . . though I have to admit, he suffers extreme bias and credibility issues.
He makes that outrageous claim, that Kenneth Walker never fired a gun, without supported said nonsense.
