If current gun legislation proposals are any indication, they're far more interested in getting "those evil weapons of war" off the streets in general than stopping individual mass killings
B) Ironically enough, the gun lobby will probably do a pretty good job of preventing the exact scenario you're describing. The NRA works for the manufacturers, and Colt has no intention of being put out of business by Hewlett-Packard. Expect some version of the RIAA/MPAA for firearms manufacturers to come about in the next ten years, only they'll be able to go after tangible products instead of solely digital files. The same guys you're cheering for now are going to be the ones suing you for $2 million and looking to get you jailed for ten years if you're caught with an AR lower receiver that you "printed" without paying the appropriate licensing fees.
and B) Thanks for putting words in my mouth but for the record I am not a member of the NRA, nor do I support ANY lobby for any purpose. I simply believe that gun control is control and that the right to bear arms is a RIGHT. I dont think you understand printing. Hewlett-Packard has nothing to do with it. And a gun manufacture cannot sue or jail for using an open source CAD-file that has nothing to do with their product.
As far as the printing technology goes, the lawyers always find a way. If you really think that the future is going to entail the production of whole firearms from in-home printers without the manufacturers getting their cut, you're crazy. There's a lot of smart people with quite a bit of pull in Washington who will be on the verge of losing large amounts of money if people can download and print their own weapons for the cost of materials instead of paying several hundred dollars at the initial point of sale. I figure Smith & Wesson will come down harder on anyone caught creating and distributing any files based on their designs than Feinstein and Boxer ever could.
I want to state a disclaimer up front:
I am not a liberal
I am not a conservative
I do not own a gun
I support the right to own guns
My positions on the issue are in my mini-theses a few pages back, so I'm not going to re write anything here. But I just wanted to interject in response to this:
Broad brush painting doesn't lead to any productive dialogue, and instead hurts progress to create a compromise, from the message board level all the way up to Capitol Hill. I hate this side of politics.
I live in Chicago, one of the more liberal cities in the US. I'm surrounded by many self-proclaimed liberals, some of the hipster variety, some of the young grad school intellectuals, some of the low income grunt workers. Guess what? Absolutely none of them want to live under an overprotective government, to have a socialized nanny state become our reality. Everyone is strongly independent, and the city is filled with hard working blue collar and white collar people alike, and don't want government intrusion. But they are completely opposite of the conservative mindset in terms of politics.
So this notion of the lazy liberal who wants daddy government to take care of them that is repeated ad nauseum is such a trite, unproductive, misleading claim that I wish would stop being thrown out as fact. Just because there are a couple examples of it doesn't mean that this is what everyone must think. In regards to guns, I have a liberal friend who owns a shotgun and a pistol. He's not looking for the government to confiscate all guns. And I'm sure there's tons more like him.
Ultimately, I'm hoping that these false, stereotypical claims about liberals and conservatives, or libertarians, progressives, and all types would stop, and actual discussion started, instead of everyone creating strawman arguments and deflecting from the actual discussion thats needed. Like I said, I support gun rights, but think something can and should be done to help curb the escalating violence with guns. I'm still waiting to actually hear a proposal, other than heavily arming the populace, that the uninhibited gun rights proponents think would help the problem. Nothing has been proffered to date that I've seen.
