That’s why informed public debate is not about adding warning stickers to things, it’s about creating competent laws that robustly protect the public.

In your example, the result shouldn’t be warning stickers, it’s laws specifically against building guns with your 3D printer. Or if right to weapons happens to be enshrined in your constitution, it’s aboyt legal liability protocols being amended to take into account the fact that a perpetrator used a weapon that they built in their 3D printer as opposed to a regularly procured weapon.
