To all of you attempting to go down the 'it's a tool' or 'without context everything is neutral' line of argument. Seriously, you just shot yourselves in the foot (pun intended). Whereas with the other 'examples' you give (syringe, wheel, hunting implements, etc.) there are clear uses that are not related to killing, maiming or otherwise harming human beings, guns and equipment of the type on display at this 'show' clearly have no such alternate use. The whole basis for the show's existence is the enabling, through sale of arms, of the destruction of other human beings. The idea that, somehow, cluster bombs, automatic weapons and missiles have a non-lethal use that might otherswise justify their existence is laughable at best and delusional at worst. Besides which, if you want a 'context' just look at the show itself, that gives them context and that context is clear: buy this equipment to kill people (or enable you to kill them more efficiently, etc.).
Don't try to conflate this with arguments about gun control either. This is not about domestic control of firearms, it's about the proliferation and sale of arms to those who wish to meet out destruction on a national, or international, scale. Whatever your views on an individual's right to bear arms, it is not even close to a position on one country's 'right' to attack its own, or other countries', citizens.
The problem I have with The Register writing articles like this is not necessarily the equipment itself, but the show that they are giving advertising to.
I can see why The Register might see it as a 'cool' idea to cover this show. It often runs articles on tech-related military stories and this might seem like a natural extension of this. It is not. The only reason this show exists is to explicitly encourage the sale and use of these pieces of 'tech' where the only aim is to oppress or otherwise harm human beings. By having a presence and reporting on the contents of the show The Register implicitly condones the sale and use of those weapons and equipment. Trying to pretend otherwise is self-delusion, you're mentioning the show, you're giving it free advertising, you're condoning it.
Note I'm not jumping up and down screaming about feeling sick or attempting to impune the intellect or personality of those posting here (or The Register for that matter). I just hope that The Register has thought long and hard about the nature of the beast it has just implicitly condoned and that it has a reasoned line of argument it can report here about why it feels it is not participating (albeit implicitly) in the promotion of the international arms trade.
