US police-caused deaths seem to run at the rate of several airliner's worth of people a year. The problem seems to be the exact opposite of a safety culture: there is no systematic review of what happens, what factors led up to it, what could have been done differently. The police routinely lie about events with no consequences, even when contradicted by video or other evidence.

We cannot even get the police to agree that the deaths represent failures: they will usually dig up or even fabricate anything negative about the victim to imply that he or she deserved to die. You can see this happening in the comments here too.

It is not suprising that people want to ground the police.
