I am going to try to write my response in a coherent manner but as a police officer I have a lot to say on this subject so I will try to keep it short and sweet...
I went through and read a few of the articles from the NY times so I would be a little bit educated on this subject.
As police officers we are taught to eliminate the threat. From what I have read Mr. Bell was in his vehicle (a lethal weapon) and driving. Mr. Bell drove his car at the officers. This put them and others in the area in fear of receiving great bodily harm or loss of life. This gives us the right to stop the threat. I know the # of shots fired sound excessive but our accuracy goes down with adrenaline and I would imagine the officers involved were trying to elimnate what they perceived as a threat.
I am sorry you feel that profiling occurs. Sometimes it is a matter of population. In my town we have a high Hispanic population, therefore it our stats coordinate with that. What that means in numbers it shows we stop and arrest more Hispanic people but they are a higher percentage of our population so it all coordinates.
I hope this helps a little bit and I am sorry for what Mr. Bell's family is going through. But there really is two sides to the story.
