To extend that: according to my understanding of a discussion I had with my cousin (a police officer in Australia), threats of a violent crime are recorded as a violent crime, as far as statistics are concerned there.

That is to say, "I have a knife... give me the money" is the same as stabbing someone, even if there was no knife.

In the US if you walk into a convenience store, say that you have a knife or gun, and take the money, that's recorded as a violent crime.

Thanks for the information. I guess I didn't really come out and say "I don't know how it works in other countries", but I imagine that it's the little things like that, maybe differences across all countries, that make this kind of thing really hard to easily quantify.
