According to the Prison Policy Initiative, a criminal justice think tank, in 2019, U.S. police killed 3.35 per 1 million people. Canadian police, the next highest on the list, killed 0.98 for every 1 million. And police in England and Wales rarely kill civilians, at a rate of .05 per 1 million.
In other words, police in the U.S. kill people at a rate at least three times higher than Canadian police do and at least 60 times the rate of police in England and Wales.
