Would a firefighter run into a burning building to do his or her duties if they had to worry about being personally sued because the house was on fire?  Would they be held negligent if their house was damaged by the fire?  Would a police officer, if being shot at, be sued for defending theirselves?  If an abled bodied surfer went out to surf big waves, hit their head began to drown, Lifeguard paddles out to risk their life to safe them and the victim drowns, should the lifeguard be open to a frivolous lawsuit?
