Maybe one could buy dozens of Glocks in the US, but as I keep pointing out there are other countries. Now, I see that some 3D plastics retail at 3USD per kilogram. That may not be the relevant plastic but it gives an idea of the prices we are talking about. Even at todays prices - they will fall - a terrorist group wanting a hundred weapons who main purpose was to threaten could use the current stuff effectively and economically.

Now, I'm not in a panic - I know we are at the early stages of all this stuff. But that's all the more reason to reflect on it before it reaches the point of being a serious problem.
