FC has some really good points on the RA deal and the TT would be well advised to set up a system to look at the course from a spectator and competitor point of view on a regular basis.
I do think however that any conventional modern risk assessment would result in non of the road races either at the TT or in Ireland being run. There is simply no way to reduce the risk down to anything that would be tolerated anywhere else in the world. If these races did not exist no one would be able to get them started today. I have only been to a couple of TTs but had the luxury of having a photo pass so I have been to dozens of the top viewing spots and all them have many dangers for spectators.

The TT is simply a dangerous event and there is a real limit on how safe it can actually be made. That said I think a better job needs to be done AND it sound like the group that has been running the TT for the last couple of years is moving in the correct direction.
