Per capita vs absolute numbers seems particularly relevant here.

There are four times as many people in the US.

Germany has four cities with around a million people.

The U.S. has at least 15.

Also, absolute numbers don't reflect justified shootings, which is an entirely different and much more nuanced conversation.

No part of this should be taken to mean that I don't think there's a problem in the US, I just object to complex issues being overly simplified.

Per capita vs absolute numbers are not especially relevant in this case. The figures differ by orders of magnitude.
