Yeah we're never going to know every detail/variable so let's work with what we do have. You mentioned England, here's a report on London that became very controversial. Even though some things might vary does it still come down to basic logic that if gun(and knife)control worked there would be far fewer homicides in London than New York?The saddest part is we do not have enough commonality on homicide reporting. Know how England keeps their homicide rate low? It is not considered a homicide and reported until the perpetrator is caught, tried and convicted! If they did it like us their homicide rate would more than likely exceed that of the United States!

Back to Sweden, they have guns but pretty strict controls and what's happening there for a few years now?

And while perfect reporting/accounting doesn't exist there are reasonably credible sources for some info, when this list is read remember Mexico has pretty strict gun control.

What's sad is that many, possibly more every day truly believe only more gun control, up to the point that only the Gov. should have guns is the only answer. Of course most of them also believe in unicorns and have little if any knowledge of history.
