One might want to question your eyesight as well as your comprehension. Nigel comedically compared a past poster with the recent tragedy where storm chasers were killed. No link was given so it's hard for me to confirm if his story is the same as the one you proclaimed it to be.
The story I am aware of makes no mention of any chasers being a hinderance to rescuers or first responders. In my understanding there are many cases in which storm chasers become the first responders and assist in saving many lives.
