I've actually researched this topic rather extensively over the past year.
By the numbers: US police kill more in days than other countries do in years
Police firearm use by country - Wikipedia
(there are numerous links that will show this same information, but for the sake of brevity, I just posted these two...)
It shows the complete list of countries and which ones have their police routinely carry firearms. When looking at those, and adjusting for population sizes, we're still light-years apart in terms of police force.
Keeping in mind that for the US, the number is about 1,000 per year on average.
Denmark: All police have carried their sidearm on-duty since 1965.
Total people killed by police per year: ~4
Adjust population size to compare to us: 231 (around 1/5th of our number)
France: Police are regularly armed
Total people killed by police per year: ~14
Adjust population size to compare to us: 70 (less than 1/10th of our number)
Germany: Police are regularly armed
Total people killed by police per year: ~10
Adjust population size to compare to us: 40 (less than 1/20th of our number)
Netherlands: Police are armed around 50% of the time
Total people killed by police per year: 3
Adjust population size to compare to us: 58 (roughly 1/20th of our number)
