Yeah, I do understand that, but you may be giving people the false assumption that they will be safe if they do as they are told, even in the face of a tornado that has a low survivability rate. If people believe that they will survive if they go to an interior room, even though the tornado isn't going to leave anything on the foundation, you've just given someone who may have lived if they would have ran away the wrong advice. If they think 'well he said I'm going to be safe' so I guess I won't try to run from the storm.
I'm probably not wording it right, or something though, sorry.
