Just a note, that canister bears striking resemblance to the ones used to hold reloading propellant.
I suppose as a much maligned Yank (from one of the original 13 no less) I should address the gun debate. Don't think I can't see the humor in this though, that is a very undignified pose to be caught in while handling a firearm, and most people experienced with firearms would be quick to inform him that he was being a hazard to those around him.
However on a more abstract plane, as I see it, many Americans are just more keenly aware that there have been, and will be, times when the collective bargain just doesn't pay off. Sure, things like government and society are nice as far as they go, and in many cases are well worth paying into, but their ability to give the individual a meaningful return on investment is limited, and not always reliable.
To keep this lighthearted, let's say the zombies come, in lieu of some other unforeseen catastrophe. The bodies of the dead rise and walk the earth seeking human flesh to devour, their victims joining the hard as they fall. Governments crumble and the world is thrown into chaos. In this scenario, it doesn't matter that you voted, obeyed the law, payed all your taxes, and were otherwise a good and loyal citizen; It doesn't matter that you were supposed to receive the support of police forces, armies, a medical infrastructure, and the best research apparatus money could buy; It doesn't matter that you trained for years, at great personal expense, to become a specialist and fill one of society's greatest roles. In this end you are left with nothing but what you can do by yourself and provide for yourself. There is no one else left to intervene on your behalf and ensure that your rights are respected.
That is why I believe people need guns, and why many Americans, as citizens of a younger nation born out of conflict, desire to keep and be practiced with firearms. They aren't to shoot neighbors who wrong us or to stage an overthrow of the government or even to play sports with, they are just tools that help make us a little stronger and a little more independent, in order to help preserve the balance between the collective and the individual, so either way we don't slip through the cracks.
I know that all makes me sound like a survivalist nutcake, but I'm really not. I just don't have the arrogance to believe that my country is so perfect as to be rendered eternal and invulnerable (stereotypical US Right), or that it may be made so by more completely devoting myself to its service (stereotypical US Left).
Flames, since fire is a tool as well.
(I think I just used up my entire run-on sentence quota there :-) )
