Courts are not inconsistent, they are following the law. Like most cases decided by SCOTUS, they are deciding on the rules set by Congress and courts have ruled time and time again, that Constitution gives Congress almost sole jurisdiction for determining how Copyright law functions.

For copyright law, Congress does not expressly allow secondary liability for third parties FOR COPYRIGHT unless the party induced the infringement or the provided service is tailored to that infringement. In this case, Cox was not cutting off copyright infringers BUT since their service could be used by same infringers for valid use, they didn't have to.

For arms producer, Congress has exempted them for liability and courts have ruled, yep, Congress gets to make the rules here.

Congress could overturn both rulings by changing the law.

This is what we want. Congress makes the rules, courts interpret but don't make new rules.

Well this is a copyright case and guns aren’t. Couldn’t that be a big reason for the difference?

Because intent isn't something that you can acquire from the actions of third parties

Second, the VAST majority of guns in the US sit in gun safes and closets and never shoot anyone.

Finally, shooting someone is not necessarily an illegal action -- gun manufacturers market their products for self defense or sporting reasons -- I have never seen one market their products for use in criminal acts.

There are around ~500 millions guns in the US according to a quick Google.

There's a lot of crime in the US, but I doubt even 1% of the guns have been used in a crime.

Also you can buy a gun and just shoot it at a range.

Even the lowest estimates (the National Crime Victimization Survey) estimates annual defensive gun uses in the US at 60-80k per year. Highest estimates are at around 2 million.

But even then, most usage is at ranges, and far outstrips crime usage.

Statistically speaking, most guns are not used for crime, and even among uses, crime is probably small compared to military or even hunting etc.

That's not at all what this ruling says?

To win, Cox did not need to prove that they sold their product without intent to infringe. To win, the plaintiff would have had to prove that Cox had intent. The difference in burden of proof is in practice massive.

This is an instance of begging the question "if the overwhelming amount of used guns are used to accompany crime then how can you argue otherwise".

But there's no substance to your premise. 400 million owned guns, 50,000 deaths a year, it's a long way from the overwhelming majority.

> where overwhelming amount of USED guns are used to accompany crime

I do not think this holds up to a factual analysis if you look at any cross section of defensive gun use reports. I don't think that parts actually relevant here though. If you were to use a similar standard as the USSC court applies here: Impressions don't matter to qualify for inducement. The action must be actively invited.

it would help if all cases of self defense were cataloged. Right now it only hits the stats if a crime is not averted.
