the more people own guns means that more people will get killed by a gun  It's so much more complicated than that, and it's really difficult to use statistics as a good argument for or against gun ownership, because there are so many different effects gun ownership has that are very difficult or impossible to keep track of or measure in any meaningful way. Using "more guns = more gun deaths = guns are bad" is as bad an argument as "more blacks = more murders perpetrated by blacks = blacks are bad."
