Worse than that, there's two of them going on on the frontpage right now, one in here, one in the thread about glasgow carpark gangstas.
I'll just report a comment I made 5 months ago when this happened:
"THIS debate definitely does not belong here. Seriously, even if humankind ever does sort out the essentially intractable problem of governmental control over the carrying of lethal weapons by the citizenry, I am willing to bet everything I own that we won't be sorting it out here on Hacker News.
I reckon we could have a fucking boring argument about it though. I've seen it done, it looks easy."
