Happy to see some good replies here. Yes, it would mean that we’d need to hold car makes responsible for DUIs, Cutco responsible for knife attacks, even baseball bat manufacturers for violent attacks done with baseball bats.
It could also hold companies responsible even if they aren’t actively manufacturing the dangerous item anymore; for example, let’s say that Smith & Wesson stops manufacturing guns. Their guns will still be out in the hands of folks, and they will still be held accountable for the violence.
Edit: To respond to this:
Guns were made, by design, to be effective and efficient at the ending of human lives. Using the firearms in the way they were designed to be used is the primary difference for me
At a very basic level, guns are designed to, I would argue, send a bullet somewhere. If the gun reliably fails to do so (i.e. it jams constantly), or inappropriately deploys the bullet (i.e. it explodes in your face, shoots backwards at the shooter, or is wildly inaccurate), then I could see why the manufacturer could be held responsible, since the product isn’t doing what it’s supposed to do.
You can download relatively good sounding audio from YouTube but you need to be using the right format in YouTube-DL, which not all downloaders do
