He obviously hasn't read John Lott's book on how guns prevent crime more than 2 million times a year just in the US. He doesn't know that they are rarely fired, that just the sight of a gun in the hand of potential victim stops the criminal cold most times.
But of course he wouldn't know that, believe it or let it stop him from his smug, self-righteous, condescending and cliched, "liberal" fantasy.
Great, a girly-man Bond.
The source of the "up to 2.5 million defensive uses per year" statistic is Kleck's famous study done back in 1986. Lott's study focuses primarily upon the effects of concealed carry legislation on violent and property crime rates.
