This is a question that is now being asked by the media (finally), in the wake of the shooting of unarmed Michael Brown in Ferguson, Missouri.
Here's an example from the DailyKos.
From the article, an exhaustive review of the available data:
"If the use of kicking, punching, tasering and pointing guns at citizens is felt to be excessive an average of 74% of the time - and is Three Times Higher for Black People - just what would the percentages of unjustified, excessive uses of deadly force really be like if we had those numbers?
Could it be as high as 80%, 90%?
"Could it be so bad that the obviousness of it all would be plain for all to see? Just how bad is it? Maybe that's why, with all this number crunching already being provided by the BJS and Police
Departments and the FBI - we still don't have that. one. strategic. figure.
"Somehow I don't think that's a coincidence."
What we do know is that police are more likely to stop a black person, detain a black person, question a black person, search a black person, arrest a black person, use force against a black person, and use excessive force against a black person. Perhaps the rest is obvious.
And while I still will not draw any conclusions about the officer in this case, until all the facts are known ... there is this!
