But are homicides down overall? What's the purpose of banning firearms if they don't prevent murders? Because if we compared home invasion rates (and perhaps some other categories), I'm guessing they'd look drastically lopsided. In the US state where I live 80% of those convicted of home invasion said they carefully picked a house where they believed the owner was not armed. And the news often carries stories of people stopping assaults, rapes, and home invasions with their personal firearm, nearly always with no one being harmed. These stats are of course not recorded.
