I'm sure many wont even click on your article to read it...as it may, (pause for effect), have an impact on their viewpoint.
The article (or study I should say) does give some support for the fact there is some level of racial bias (call it whatever word you want, racism being the strongest term which I think is overused) due to the fact that blacks and hispanics are more likely to have a physical altercation with the cops vs. whites.
I sympathize with the minorities in this country. I do feel there is an element of privileged and non-privileged when it comes to race and how we are treated by those we come into contact with on a daily basis. I also have seen way too many times that those people who take ownership/responsibility for their actions and who treat others well and work hard are successful people - regardless of race and often regardless of what situation they were born in. I still do sympathize with those who have a tougher mountain to climb due to factors out of their control - I feel that for all races because poverty is certainly color blind.
My own experiences with cops has been limited. On two occasions in my life have I ever interacted with an officer in which I was the one being questioned...one black officer in Taliaferro County, GA was as nice as he could be to me and one white cop in Cobb County, GA was a complete d*ck....and I'm a white guy. So it really leads me to the fact that cops are made up of the general population - and the general population consist of great people, honest people, servant leaders, jerks, racists, good parents, bad parents, those subject to addiction, and every other trait you can think of. No other job in this country requires what the job of a police officer requires and so they stand out like a sore thumb vs. say accountants as a whole, teachers as a whole, etc. - and I think what this article shows (and other statistics I've seen) is that when it comes to life and death situations there is not a racial bias....but when you look at the OVERALL picture, then yes, there is a racial bias that shows up....but not quite on the level it is portrayed.
Moral of the story? Impact your small area of influence in life for the better and Treat others as you'd like to be treated
