No, it really doesn't. German shoots and kills, on average, fewer than 10 people per year. The total amount of bullets discharged at people hovers around 50 to 60.
In a country of 83 million.
The US population is four times larger and the number of victims of police shootings is literally 100 times higher. An estimated 1173 in 2024 and the US internationally doesn't even properly track this number.
Heck, even France's police kill significantly more people than Germany's "trigger happy nazi cops".
Germany, like most countries, does have issues with law enforcement. But, as you noticed, so far our checks and balances hold - at least when it comes to fatal violence.
I don't think you can extrapolate any trend from the extremely low annual numbers. 2024 was indeed an unusually violent year (even though official stats haven't been finalized afaik), but looking at 2025s numbers so far, this does not appear to indicate any trend.
