'Mericans are so sue happy.
So if a 'merican woman is hit and injured by a car or a round from a gun - she'd sue the car manufacturer or gun maker? She can't sue the gun makers as Congress has made them a protected class. Most car makers including Tesla are still grappling with the liability angle of self-driving cars, let along the current meatbag-driven (non-AI) ones. Currently they're only on the hook if their cars are inherently and provably defective.
I can understand going after the deepest pockets: Apple and the stalker's insurance provider, but that's civil rather than criminal law. The stalker is the one at fault.
