In reply to baynes:
I know you've made the point that you're not interested in blame culture and compensation but the 'disclaimers' that you sign are not worth the paper they're printed on in cases of negligence.
IF the wall was at fault with bad matting ( and i'm not saying they are in any way ) they are responsible. You are not disclaiming their responsibility to Health + safety.
PS you're not interested in compo - but is she ?
If she is then look at the incident again and don't automatically assume they weren't at fault. I agree climbing does not need people sueing for nothing but neither does it need bad practice at walls.
