I don’t understand what statistics have to do with this.
It might be possible that the quarantine and economic hardships are a factor at play, but the ultimate causative factor is that non-white Americans are tired of both the veiled and bald faced racism and mistreatment that is a daily issue.
The protests aren’t just about cops killing black men; they’re about every single aspect of daily life being made more difficult because of constant racism and abuse.
But in particular I don't believe that the protestors are worried about police vs forestry fatality statistics.
