I've heard Wallenda complain about it, but I haven't heard him make a case for not wearing a safety harness. The only difference it seems to make is whether he falls and lives or falls and dies.
Is this stunt about his skill or is it about his death defying stunt? Any damn fool can try a stunt that risks his life. But I doubt many people could walk across the wire under the conditions Wallenda will be faced with.
However, if he is performing the stunt just to risk his life, then the state should withdraw permission for his stunt.
Either he can or can't make it. If he falls, we don't need him to die to prove he couldn't do it. The fall will prove that. The harness will just eliminate a senseless result of the fall.
Then again, I would like to know whether he is a screamer or arm waver or both.
