Carpenters know measure twice, cut once.
So what happened with the luge track design?

The IOC may consider the track safe but the absence of barriers to prevent collision with columns certainly seems like negligent design.

I recall the Toronto Don Valley Parkway where lighting columns were installed in front of roadside crash barrier guard rails, when they should have been installed behind the barriers. Morton Shulman the Toronto Coroner made a strong case for negligent design in this case. http://en.wikipedia.org/wiki/Gardiner_Expressway

Vertical protection against collision with columns needs immediate installation, no need to wait for any lengthy inquiry.
