All other developed nations have significantly lower rates and incidences of police killings: https://www.prisonpolicy.org/blog/2020/06/05/policekillings/.

If you dig around most other nations have substantially lower rates of LEO homicides.

I think one begets the other in a positive feedback loop that is difficult to break.
I think there are way too many police killings, but we should get the context right
Robbing a bank should not be a reason to be killed either...unless people lives were at risk.
I want to reduce police killings, but not neuter them.
If you do, then you end up with powerless police, which will make matters worse for everyone. E.g. murders in Baltimore https://homicides.news.baltimoresun.com/?range=2014
Look at total for 2014, 2015 and 2020. Up until 2014 you had less and less, with just 211 in 2014. In 2015 you had 342 and later years about the same.
What happened in 2015? Police killed a suspect in custody and protests ensued. Was it right for police to murder a suspect? Surely not...but now you have 100 more people killed each year in the city...600 extra people died in Baltime since those protests.
Those policemen got away with no convictions. The police from 2020 are not walking away from cases like that, so my bet is that we will see a worse wave of murders, this time across America.
