International comparisons for crimes with vague definitions are hard, and I don't think those numbers are effectively comparable.

Have a look [1].

'Murder' is a straight forward thing to define. Someone gets killed.

But 'assault' is a very vague thing.

According to that list 'Iceland' is a crime ridden country with overall crime 4x more than the US, even though murder in the US is more than 10x greater?

More like reporting, charges, definitions, data collection is different.

That said: Montreal is slightly sketchy for petty crime, and some places getting drunk and fighting is normal (UK/Nordic) and in some places, they use knives (i.e. Wales, Scotland).
