The death on Goliath was because the woman had a pre-existing anyeurism (SP), not because of anything the coaster did or failed to do. The specialists said she could have died while sleeping just as easily.
I agree that the media blows these sorts of incidents out of proportion, not that they don't deserve any attention. Perhaps it just seems all the more horrific because amusement parks and carnivals are places you go to have fun, relax, and so forth, not something that routinely has accidents (IE, the highway). No accident is ever routine, but these may have some sort of special quality about innocence gone wrong.
