I have friends and family members who are cops. I can't speak to the specific cases you posted AB, but I can tell you that EVERYONE who I know who is a cop (4 cousins, and another 3 friends) uses race as a huge determining factor in the cities they work in. The majority of them work in the greater LA area. Usually, its blacks I hear them speaking about. Though they'd never admit it officially, they take into consideration race in their daily work. Do I blame them? Nope.
