Fifth Circuit Declines to Enjoin Regulation of Online Publication of 3D-Printing File

People you are missing important information about the Liberator it isn't any more a gun than any short piece of plastic pipe is a "gun".

When the Cartridge is fired the bullet starts it's travel down the plastic barrel. The bullet traveling down this plastic barrel risks the chance of splitting the barrel, or the cartridge breaking through the back and into the shooters face. With all luck the bullet travels forward.
Now the compressed gasses forcing the bullet forward have the same ability too blow the barrel apart or cause the bullet to tumble ripping the barrel apart traveling out in a undetermined direction. Without a solid metal barrel the gasses leak from the loose weak plastic barrel causing the bullet to leave very slowly tumbling due the not having a solid barrel twist where the bullet will go almost anywhere and not very far at that. The Liberator's bullet will emerge going very slowly and wobbling or tumbling due to lack of spin. It might go almost anywhere, and is unlikely to do much damage to anything it manages to hit.

This 3D Printed thing does not even compare with a "Zip Gun"
Which by the way is legal in the USA

All news about the 3D Printed guns are highly exaggerated on both sides.

As long as you incorporate some cheap metal parts, 3d printed guns are a viable option.

Wonder when the first high school shooting with one will happen.
