Live by the sword, die by the sword

Look at this: Protection Or Peril? Gun Possession Of Questionable Value In An Assault, Study Finds.: "on average, guns did not protect those who possessed them from being shot in an assault. The study estimated that people with a gun were 4.5 times more likely to be shot in an assault than those not possessing a gun."
No surprise to those of us whose reading of the gospels leads us to think that we reap what we so and that living by 'the sword' is to put ourselves in harm's way; not to deter.
Of course, there are some politically rightist Christians who appear to disagree about that, but it's interesting that this research seems to question their dismissal of gospel imperatives in favour of a version of Luther's two kingdoms theology.
