This article broke down the claim in relation to police shootings in the year 2019:
https://www.usatoday.com/story/news/factcheck/2020/06/18/fact-check-more-black-people-killed-police-than-floyd-protests/5323116002/
"The claim: More Black people have died in Floyd aftermath than in police shootings in 2019.
"The claim in the post has been rated FALSE. In 2019, 14 unarmed Black people were fatally shot by police. Fourteen Black people have died during the protests, but not all of these deaths were directly caused by the protests. Six of the deaths are either unrelated or the relation to protests is under investigation."
It stands to reason that if 1 year of police shootings is false, then 10 years of police shootings is roughly 10x as false
And now you know.
I'd love to see what "facts" Candace Owens is relying on.
