I think in US police know that their adversary is very likely to have a legal weapon that they are carrying so they take no chances and shoot first and ask questions later. This can lead to these higher numbers. Do you have a right to legally carry a weapon in Finland?

Also, I agree with you about assholes in the Police. I think police jobs attract people with power obsession so when they are given the legal right to be the power freaks they play it to the max. My interactions with police here were few, but always unpleasant, except one time when the female policeman stopped me when I was leaving the gym and told me that I forgot to turn my headlights on. She was nice and didn't even give the a ticket...
