I think total killings are pretty accurately reporting.

There were about 1100 police killings in 2019. This includes people shot or beaten to death by officers on or off duty. [1] About 10% of these people were unarmed. This statistic is the one which is most likely under-reported. About 50 police are feloniously killed per year [2]

Thank you.

I feel like they probably always report them but lie about the circumstances and say the shooting was justified.
