US, and no, I didn't need to check the statistic. Do you also think people shouldn't be protesting because they haven't proven black people are being targeted disproportionately by police to a 95% confidence interval?
I prefer to base my views on facts. You need to check the statistics because it's very easy to be wrong - we all have biases and limitations.
I gather statistics show USA police are not targeting black people ("damn lie and statistics" though, so I'm Caruso's about that result), contrary to how I imagined it. That doesn't mean there isn't a problem, it possibly means the problem is more concentrated - ie in general the police are doing well, but specific groups/officers are being highly discriminatory.
