this is one of those statements that is too ambiguous for the internet. It's hard to know if you are being sarcastic? Attempting satire? Or you are trying to make a joke, or genuinely don't know what you are talking about. So, can you clarify?
No I am serious, if you are comparing murders, you should include all weapons!
There are regional differences! Fire arms are heavily regulated and relatively hard to get in EU. We are close to war zones, hand grenades are easier to smuggle, and are used in Sweden.
If you include murders by knife, London is worse than US!
Edit: also you wrote "assault" that could include anything from armed robbery without health injury, to self defense. Apples and oranges!
ok I've updated it to show that I mean "fatal" assault by firearms.
Quick google search brings up the following
"All in all, there were 77 incidents of detonated hand grenades in Sweden during the six-year observation period, in which nine individuals were injured and one killed."
is this what you are talking about? Doesn't sound that dramatic.
Seems like you are just trolling. Especially with the throwaway account, hard to take what you are saying seriously.
