Not accurate at all. That graph is obviously old. Our current murder crime rate is 0.37 per 1000. Not 0.49.
We (of countries that are capable of reporting stats, which doesn't include most of Africa, South East Asia and South America) have the ninth highest murder rate.
Here is a newer graph.

To illustrate how much lower we probably are than 9 notice how many countries are missing or haven't reported stats for many years, or report ridiculous stats that don't match anecdotal evidence. Countries like Somalia don't even have functioning governments or police forces. I would suggest we would probably still be in the top fifty for murder if all countries had the ability to report stats. So it's nothing to be proud of. But we're hardly the "murder capital of the world" as some drama queens like to go on about.
But yes, I think in essence it's silly to say crime here is nominal. We clearly have a very high level of murder. I wouldn't deny this. But I would reject anyone middle classed person seeing themselves chiefly as the victims. The gross majority of murders are drunken disputes turned ugly. Not "hijackings" and "house breakings" and the true "terror" crimes. They make up around 500 of the 18000 murders according to police.
