I lack the composure to make any insightful comments here, mainly because the Twitter reportage on the BBC included a summary that it's a pretty rough neighbourhood, and things like that aren't a surprise?!

Sorry, what? There's a part of the world where a mass killing in a civilian, entertainment space occurs and you f*cking say this could be *expected*?!

And the idea that someone could have shot back is utterly bloody mental. For pity's sake, people, if guns were a wee bit harder to come by, you think this would have happened?
