Actually, a quick look at this is kind of entertaining. In order to minimize the difference in violent crime between the US and Japan, for example, this paper tries to group murder and suicide together. Seriously?
It also does exactly what I expected, which is try to make the US look good by contrasting it against poverty-ridden countries, even though overwhelming evidence indicates that poverty is one of the most important factors in terms of crime ratio.
Some of the facts are actually correct, once you strip away the spin, but you can read much better papers elsewhere that actually discuss the context and rationale. Handgun bans being ineffective in some countries, for example, because those countries have been unable to stop the influx of black market alternatives. However, just throwing information out as little bits of "fact" makes this a waste of time for anyone who actually wants to understand anything.
