US government orders removal of Defcad 3D-gun designs

The BBC’s Rebecca Morelle saw the 3D-printed gun’s first test in Austin, Texas
The US government has demanded designs for a 3D-printed gun be taken offline.
The order to remove the blueprints for the plastic gun comes after they were downloaded more than 100,000 times.
Opinion:
That’s my guess, it’s too late.
100,000 accesses/downloads, it’d be like using a bath plug to stop Niagara Falls.
For me personally, I don’t care. I’m not interested. In all probability criminals and terrorists aren’t interested either; they want the real McCoy. Not some mock-up they may or may not blow up in their hands.
School kids may be. They’ll want to experiment as I did with chemistry.
The horse has gone, don’t bother shutting the barn door.
