There's something to be said for a well-armed militia - what the heck do people think the 2nd Amendment was all about in the first place? Aside from that, there is one thing missing from this article : what the crime rate is in Darra. I'll bet any form of burglary is unknown, as is the occasional passing insult.
I agree it's probably small. The article said vendettas were held for generations. If I lived there, I'd keep my mouth shut and mind my own business.
