Who decides who was 'wrongfully' killed? For example to me (as well as grand jury) MBrown was rightfully killed. To the BLM he was not - so we're stuck. Even if that can somehow be quantified, do we have statistics for the number of white people who are wrongfully killed by the police? One metric I saw (unfortunately don't have a source) is that this year 3% of whites AND 3% of blacks were killed while unarmed.
