The ATF Not Concerned About 3D Printed Guns... Yet

derekmead writes "3D-printing gun parts has taken off, thanks to the likes of Cody Wilson and Defense Distributed. While the technology adds a rather interesting wrinkle to the gun control debate, the ATF currently is pretty hands-off, ... 'We are aware of all the 3D printing of firearms and have been tracking it for quite a while,' Earl Woodham, spokesperson for the ATF field office in Charlotte, said. 'Our firearms technology people have looked at it, and we have not yet seen a consistently reliable firearm made with 3D printing.' A reporter called the ATF's Washington headquarters to get a better idea of what it took to make a gun 'consistently reliable,' and program manager George Semonick said the guns should be 'made to last years or generations.' In other words, because 3D-printed guns aren't yet as durable as their metal counterparts, the ATF doesn't yet consider them as much of a concern."

A 16" shotgun did enough damage that I felt confident it would kill a man. I have spoken with law enforcement officers who collaborate that. Shorter barrels spread the shot out more and make it more... painful, or so I have been told. A sawed off shotgun is not so much about self-defense as it is torture. Imagine the skin and half the bone from your torso and face being ripped off while you slowly, painfully, bleed to death. The last time I fired a shotgun I blew away a stack of cans and half the tree stump they were stacked on.

      Again, this is just what I have been told. I stick to pistols. I have no need for rifles, "scary-looking assault" or otherwise, or shotguns. The SCOTUS has been fairly consistent with regards to affirming our right to bear arms that are suitable for self-defense. A pistol I can conceal or wear openly on my waist and that is easily maneuverable in close quarters such as my home is ideal for self-defense.

What feed and speed? What are you going to fill the "lube reservoir" with - cause you know, what works for one metal may not work so well with another? But I'm sure you've got all that figured out, cause you 3d-printed something that one time.

    But there are a bunch of people talking out their ass as they haven't a fucking clue about the first things about firearms. plastic printed guns are the NON STRESS parts, lower on a AR-15 the grips ect. the internals all need to be made of steel, and assembled properly (even if you could print them all together, an AR-15 is complex on the inside with many small springs) Laser sintering, the parts are going to be porous and need to be filled in, and then heat treated with a forge not your every day oven (unless yours can get to 1300 degree's+). the barrel needs to be of sufficient strength not to explode during the first round. (ie stand up to pressures from 35,000 psi (for a 9mm handgun round) to 55,000 psi + for rifle rounds. the bolt and firing pin need to be stronger so they don't fly back into your face. Laser sintering is used for some things these days like making door handles, but after they are made they are fragile VERY fragile. they need to have bronze or other metal added to fill in the gaps and hold it together properly. none of this is going to work for a little "script kiddie" at home.

    I hear ya.

    The counterbalance is that the UK is NOT the same as the US. They are in different places in the world and have different histories.

    I personally know, and know people that know others who like to shoot guns at targets for practice just for the hell of it; they do not own and shoot because they feel the need for protection. That comes later, *if* needed. Those who are smart know that if you are to shoot someone, they must act in a manner to make you feel threat to your life first. If you aren't a licensed concealed carrier, you're pretty much limited to your home in most states. If you are to be justified in shooting someone, they must come in to your home and make you feel threatened for your life OR shoot at you first. Since this legal state is a stupid one, people may tend to overreact. When I say that, I refer to the lack of rights to use a gun on someone who you know to have one and simply feel threatened by them. If that right existed, people would feel a little less confident in acting out with a gun. Lacking that right, people feel a bit more grandiose, in that they are trying to *find a legally valid reason* in their heads to use their guns on others when they feel threatened with no recourse other than "waiting for the cops to show up". I'm sure the person who is approaching you and threatening you isn't going to say, "Oh, of course. I'll wait for the police to show up before I act out on your any further."

    Moving on...

    If you were to try and take the guns away from those who own them, the counter-response would be astronomical. Here in the good ol' US, we're used to freedom and rights. That's pretty much what it was founded on, eh? If you try to remove freedom or rights, people counter with an increased desire to HAVE said freedom/rights and to ACT to maintain them or regain them. You can't with 100% certainty say that the minds of those in the UK are the same as the US or say that the statistical data is relevant in an apples-apples sense.

    people who carried guns were 4.5 times as likely to be shot and 4.2 times as likely to get killed compared with unarmed citizens. When the team looked at shootings in which victims had a chance to defend themselves, their odds of getting shot were even higher.

    Okay, another quote from the article:

    So Charles Branas's team at the University of Pennsylvania analysed 677 shootings over two-and-a-half years to discover whether victims were carrying at the time, and compared them to other Philly residents of similar age, sex and ethnicity. The team also accounted for other potentially confounding differences, such as the socioeconomic status of their neighbourhood.

    Bad data. They are only accounting for people *IN* Philadelphia, PA. They aren't comparing gender, age, upbringing, income, ethnicity, or other factors *from other areas of the country/state/world*. Statistics do not account for hidden mental states. If they did, we would be able to read the mind by now. All they have to work with are the outcomes of the acts (in written legal cases) which may or may not have a complete set of information of the causes and effects of the individual person. In fact, they can never have a COMPLETE set of information; hell, if they did, we wouldn't really have much to talk about in this situation, would we?

    Wow, props for the well addressed, calm response. It deserves a reply.
    There were a number of areas I didn't make reference to purely for the sake of being brief, but I'll raise them now.

    I did consider the issue of sports, however that can easily be tidied up with tighter restrictions on equipment. As is the case in many (most?) other countries, the equipment isn't owned by individuals, but "leased" from the ranges. Ammo is counted in & out, so it can't go "missing".
    As for your burglary comment, I again point out that in an unarmed state it's highly unlikely that the intruder would have a gun themselves. This would be due to a) lack of availability & b) being caught in possession of a firearm can turn a 6 month sentence into a 40 year sentence.

    I can possibly empathise with people not wanting to give up their arms once they've already got them. a) for sentimentality, b) because the non law abiding citizens who have now got hold of guns, won't mind breaking the law to keep them. This leaves the law abiding citizens at a distinct disadvantage.
    This isn't an argument *not* to disarm the populace, just that it would need to be done carefully.
    You can probably draw a very similar analogy with nuclear proliferation & MAD - no one wants to make themselves vulnerable by backing down first, but everyone agrees it's a counter-productive situation that needs to be resolved. In fact it's almost exactly like MAD, except with nations instead of individuals.

    Now don't get me wrong, I'm a fully fledged, card holding civil libertarian & I'm not averse to arguing controversially strong views in support of our civil rights. However, I don't think every man, woman & child should have the natural right to possess equipment whose sole design & purpose is to kill other people.
    I the same light, I also don't have problems with the government restricting the public's access to lethal chemicals & radioactive compounds (which have legitimate scientific use).

    Proceeding onto the research & article...

    Bad data. They are only accounting for people *IN* Philadelphia, PA. They aren't comparing gender, age, upbringing, income, ethnicity, or other factors *from other areas of the country/state/world*.

    Unless the PA is a total anomaly which bears no similarities to other states, I think it's fair to draw inferences - and 667 cases isn't a bad sample size. At no point did the study overstate the certainty of its conclusions.
    As for the other factors you mention, are they relevant? The aim of the study was simple: Will being armed make you safer?

    Yes, there are still gun related crimes in the UK, that's unavoidable. However, incidents tend to be limited to the rare gang shootings on a couple of infamous council estates. Armed crimes (lethal or not) outside of this tiny subset are infrequent enough that it'll be covered in the national news for days.
    The Duggan case you refer to was a good example of this. The alleged gang member was in mere possession of a gun, having only just received it & the police were all over him.
    Our homicide by firearm rate is 0.1/100,000 (40/yr). Taking into account that most incidents are within the small communities mentioned above, I think that shines quite well on us as a whole.
