I'm not sure what you're looking for Servern. A way to prevent these deaths? You just can't. Too many people do too many stupid things. A way to keep the RRs out of court? Too many shar---uh, I mean lawyers. A fool-proof preventative? Too many fools.
Short of cocooning the entire race in bubbles and not letting them out, this sort of thing will happen. Find a more possible cause to crusade for, like ending poverty or building a bridge from LA to Honolulu.
