What I'm halfway worried about is how people who don't want to/have the time to do that examination may respond.
I just think that there are preconceptions attached to the accusation of racism in many person's minds, and that because of this, we must be careful when applying it to a situation.
That said, it certainly sounds in this case that if not racism, there was at the least bigotry against a group of people based on
The area they lived in.
The tendencies of some individuals in that area (crime rate, etc).
Based on the interview in the OP, I'd say that the majority of the police force had some kind of institutionalized misconceptions which were probably passed on to the new officers and such over the years.
The key problem is lack of communication between the police and the people in the area.
Without that communication, we get this Ferguson situation, where assumptions are made on one or both sides (probably both) and it denigrates into a shouting match, or even violence (although I don't think the violence was what the people in Ferguson wanted, except for a few outliers).
