paragraph: Not surprisingly, guncite, too, compares data from different years -- as I know from personal experience, it is quite difficult to do comparisons of crime statistics due to differences in reporting frequency and methodology. The gun homicide rates for the countries Moore mentioned, according to guncite, are: Japan: 0.02 per 100,000 (1994)England/Wales: 0.11 per 100,000 (1997)Germany: 0.22 per 100,000 (1994)Australia: 0.44 per 100,000 (1994)United States: 3.72 per 100,000 (1999) Critics fail to credit Moore with not making the same mistake that some gun control advocates make -- concluding that gun ownership "leads" to violence. In fact, Moore mentions several counter-examples, and more such counter-examples can indeed be cited. It is intuitively obvious that guns do not actually cause violence -- but it is equally intuitively obvious that they make the violence that is committed more deadly. It is the second intuition which gun rights groups like the NRA seek to obscure using fraudulent data by the likes of John "Mary" Lott. The gun control movement, on the other hand, distracts from the real causes of violence -- poverty, paranoia, the "war on drugs" and antisexuality. If these causes were addressed, gun ownership in the United States would not be a problem (but also unnecessary); just like it is in Switzerland. Canada ammunition purchase. You write: Bowling shows Moore casually buying ammunition at an Ontario Walmart. He asks us to "look at what I, a foreign citizen, was able to do at a local Canadian Wal-Mart." He buys several boxes of ammunition without a question being raised. "That's right. I could buy as much ammunition as I wanted, in Canada. Canadian officials have pointed out that the buy is faked or illegal. Once again, you fail to distinguish between regular film editing and "faking" (a word which "Canadian officials" have never used; for such a distortion, Moore would have been boiled alive by his critics). If Moore simply chose not to show how he revealed his identification to the salesperson, there is nothing fraudulent about that. He made no claims whatsoever in the film about the need to show or not show identification. His claim that it is possible to purchase ammunition in supermarkets is independent from that claim. 
question: Is the United States and Switzerland similar with their gun laws?
answer: Yes
