"guns kill, not people. gun manufacturors held liable for all gun related deaths."
This ruling says as much. Guns are, indeed, made for the sole purpose of killing someone. They may not be made for the specific purpose of murder, but they are a significant instrument of murder.
I expect this ruling to be abused against guns and many other currently lawful devices.
saw this over on slashdot
".. which means that Hollywood should be liable for promoting the use of guns for killing people whenever they show guns being used for killing people .."
it's a stretch (as are most slashdot postings) but kinda funny to consider.
