Guns are only half of the problem. To find the other half you need to ask yourself what it is about your culture that creates such a sick obsession with them.
It was more a case of omitting it because of its irrelevance than forgetting it. Although I suppose you could be mucking about mucking out, therefore making a crap job of it.
Over here to "muck about" means to mess about, to dabble with. It implies not taking something too seriously. If you were to say, for example, "I like mucking about with cars" it would mean you liked to do your own maintenance or make modifications in a hobby sort of way. If someone tells you to stop mucking about, it usually means you're not making a very good job of something and they want you to get on with doing it properly. To muck about with badgers is not something most people would readily admit to.
RE: Is gun control the solution to these unspeakable tragedies?
Of course I'm wrong, I don't agree with y'all.
