that incident was dreadful ... but it doesn't prove your claim.
- Simon
It certainly doesn't. Nor would I use it - in and of itself - to support my claim That's why professionals go out and conduct research so we can have informed opinions. And the research shows that black civilians are 21.1 percent more likely to have force (lethal and non lethal) used against them compared to white civilians with the same reported compliance behavior. It shows shows black people are far more likely to attract police attention than white people for identical behavior. It shows that a persons race statistically influences an officers decision to shoot. And the research shows shows that unarmed black people are 6 times more likely to be shot than an unarmed white person.
These are the FACTS. If you want to debate the best way to interpret them or the best way to address this societal challenge I'm all ears. But you're claim that it's just "one swallow" or an "odd incident" doesn't stand.
