In the US, police shoot dead about 1000 civilians every year, and 40 or so police officers are shot in the line of duty. Consider that there are 325 million people living in the US, and 1 million are police officers. It's completely out of control.
"There is no evidence to suggest that the officers did not honestly believe that Dorner was in the vehicle, nor is there evidence to suggest that the officers did not honestly believe they were being fired upon."
What would be an acceptable figure of those that aren’t immediately at risk of harming others being killed? What about injured? The media rightly tends to focus on killings, but what about unnecessary shootings or use of force that don’t result in death.
Currently that’s a non-zero number and we know that the man killed in this case was not a threat as well.
