>Are we like gun manufacturers who can simply say "it's not our fault that our tools are used for evil?"
It's not their fault. You'd have to be an idiot to now understand what guns are for: they're weapons designed to kill people efficiently. They can be used for good or evil, just like cars. Some guy in a pickup just murdered 5 bicyclists in Michigan; should we ban pickups because of this?
The whole thing about suing gun manufacturers is incredibly stupid. They're producing a product that is a tool for a certain purpose; if that product is used successfully for that purpose, but for killing someone who's innocent, that's not the manufacturer's fault, it's the user's fault. If you don't like that, then you need to enact laws to limit who's allowed to buy guns, instead of holding manufacturers responsible for improper usage. Using the court system to bankrupt gunmakers is nothing more than abuse of the legal system because some people couldn't achieve a political victory and get a legislative solution. If you really don't want people to have guns at all, then you need to ban guns from being sold to civilians, not allow it willy-nilly and then allow them to get sued. It's asinine. It's like allowing liquor store owners to sell to minors and then allowing them to be sued when those minors get drunk and do stupid stuff. If you don't want kids drinking, then pass a law forbidding it; don't muddy up the court system with BS cases because you couldn't figure out how to pass a law fixing the problem.
Personally, I do think we have done a poor job in limiting who has access to guns, but abusing the court system is not the answer. The answer is to pass better laws, get better background checks, etc. If you can't do that, you need to find some better candidates that people actually want to vote for.
