With every freedom comes responsibility.
Freedom of speech, for instance, does not permit crying “FIRE!” in a crowded theatre.
Limits create control to keep a society in balance.
The “Liberator” is a .38 polymer handgun 3-D printed in 15 pieces and completed with a standard carpentry nail used as a firing pin.
Without the nail, this gun passes through metal detectors. It is named after a cheap handgun dropped by the Allies into Nazi-held France.
3-D printers are increasingly common and the CAD file is already on the network.
The balance is about to shift and probably not come back. Toothpaste does not go back into the tube.
