Your original proposition was (I cut and pasted):
Unarmed blacks killed officers than officers killed unarmed blacks.
Which morphed into something a bit different....
More unarmed blacks killed cops than
unarmed cops kill blacks....which is different than what you originally said. I would further say that this one would not skake any conceptions of whether there is a problem with black citizen/officer encounters because the overwhelming majority of black citizen/officer encounters involved armed cops so eliminating such uses of force by police is completely irrelevant.
Even then, when looking at the well massaged numbers of the Dolan Consulting group.....I notice that it says essentially nothing about the armed or unarmed status of black citizens or the officers when a death has occurred.
So no, the link you provided does not support your particular propositions. Doesn't debunk them either. More accurately, it doesn't comment on the veracity of your proposition at all.
Furthermore, the Dolan Consulting Group is a training and consulting group that exclusively markets to law enforcement/public safety agencies buying their services. You have to factor in the fact that they rely entirely upon the support and purchases of law enforcement agencies for their survival in looking at their analysis. They aren't exactly an unbiased research team.
Finally, this quote clearly establishes that you are making several wrong assumptions about where I am coming from in challenging you. I just like people to support their factual propositions with....facts. If you had stated this as an opinion, I might have agreed or disagreed with your opinion. I would not have challenged you to establish the factual veracity of you opinion, though.
I am not a proponent of the "whole cops hate Black's [sic] narrative". I never have been. Hell, I've worked in and for law enforcement for 20+ years and am married to a cop for gods' sake. This week, I have been accused of being too deep in the opposite "no bad cops" or "no systemic problems" narrative by a poster on this site for exactly those reasons.
There are positions between "cops hate blacks" and "extremely extremely few cops"/ "a few bad apples" dismissal or excuse for not addressing systemic problems. There are positions between the binary extreme. There almost always are. I'm there in the shades of gray.
Thank you for calling me a smart guy...if it was sincere. There are plenty here and in my family that would disagree with that assessment.
