I think my link got messed up earlier, but this is the results: https://www.skeptic.com/research-center/reports/Research-Report-CUPES-007.pdf
Summary of Findings
1. The available data on police shootings of unarmed Black men is incomplete; however, existing data indicate that somewhere between 13-27 unarmed black men were killed by police in 2019. Adjusted for the number of law enforcement agencies that have yet to provide data, this number may be higher, perhaps between 60-100.
Yet, over half (53.5%) of those reporting “very liberal” political views estimated that 1,000 or more unarmed Black men were killed, a likely error of at least an order of magnitude (see Figure 1).
2. The available data suggest that 24.9% of people killed by police in 2019 were Black. However, across the political spectrum, survey participants overestimated this number.
Those who reported being “liberal” or “very liberal” were particularly inaccurate, estimating the proportion to be 56% and 60%, respectively (see Figure 2).
