If you mean people were killed by police, that happens every year, you just don't hear about it if the media doesn't hype it up.

But the Washington Post has statistics that clearly show there's no four year cycle to police shootings: https://www.washingtonpost.com/graphics/investigations/polic...

Just wait until 2024 and they'll pick another case to hype up. Despite the fact that police brutality happens every year and nothing gets done about it. It's all bread and circuses.
