Engineering teachers have access to lathes and mills : they could make actual working weapons faar less dangerous to the user. Yet somehow they have refrained from it, no ?

Anyone can buy a mill and lathe. I haven't seen a ban on those. I don't expect there will be a ban on 3D printers anytime soon. This is just hype piling on hype.

There is no need for ammo shells to build a projectile weapon, you can rig a very effective induction rail gun for less than 400$. We're not banning car batteries or mosfets either are we ?

So let's stop with the nonsense already.
