I recall many of those accidents were the results of miss handling the firearm. Remember people sue for their errors. There are a lot of "Bottom Feeder Lawyers," that will run with such a case. I suspect that the fact a firearm of any kind is involved raises the odds of winning against a firearm manufacture over 50%.
As a former Hunter-Safety Instructor the errors made in gun handling were used as instructional tools in classes. Example: Having a loaded rifle laying in the seat of a vehicle. (violation of the law and safe handling rules) Dragging the rifle across the seat while it is pointing a person on the drivers side.(Violation of safe handling rules.)(The dragging motion would be enough to release the Remington safety, and the safety on many other makes.) Example the British Enfield Mark 4.
