I’m no gun person, but you could easily make a gun on a lathe or a mill drill, too. Get a CNC one and you don’t even need to know how to use them.
Are we going to start fitting them with “you might be making a gun” detectors, too? Of course not.
Edit: Turns out they are… I choose to blame my ignorance on the paywall.
I know. I meant relative to using a manual machine.
You could make the same argument for 3D printers.
