I always love the comparisons to Switzerland that come from the American gun folks, because they either don't know or don't tell you that: all Swiss citizens have to do mandatory military service; all Swiss firearms are registered and people have to go through thorough background checks; but best of all, despite the fact that most Swiss households have firearms, there is no ammunition in circulation -- you have to request it in advance, not just purchase it at your local Walmart. So, sure, let's let the USA be more like Switzerland.
@Simon -- I think the comparison is supposed to be valid because the populations are about the same number, so all other factors must be considered equal. It makes a lot of sense to me too.
