In a poll done asking how many Unarmed Black men were killed by police in 2019:
The actual number is not certain but the maximum is 27.
Very conservatives had the closest with 46% answering about 10.
Another 34% of conservatives answered about 100. 20% thought about 1000.
Very liberal 15.71% thought about 10.
31% of very liberal thought about 1000.
14.3% thought 10,000, 8.9% more than 10,000.
A majority of liberals think over 1000 unarmed black men were killed by police.
The reason is media coverage. The more conservative the respondent the more accurate they are.
As to the question of what percentage of all people killed by police were Black, very liberal believe 60%, liberal 56%, moderate 46% conservatives 38%
The real number is 25%.
Yet if you don't believe the narrative you're an evil rube.
