There are all sorts of rules and regulations that hold a manufacturer at fault even if the caused injury or death was because someone intentionally ignored how the device was supposed to be used. Most of the ones I know are in the workplace, especially industrial, but I'm sure there are situations in the public area as well.How could anyone possibly think this is Apple's fault? If there was ever a frivolous lawsuit, this is it.
I don't think that Apple SHOULD be held liable, but it doesn't mean that they won't be.
