People do understand that the police put their lives on the line by stepping into a potentially dangerous situation, much the same way firefighters do.
I do, however, find it interesting that you support the article I posted, even though it contradicts something you yourself wrote earlier.
That the second cop was not properly trained.
My article says that current training isn't enough to overcome prejudice on the part of the police officers.
SO that guy? Was properly trained, and he still killed someone.
I'm looking for the FBI statistics you mentioned, if you've got a link I'd appreciate that.
I did find this though:
