1. Yes he knew.
2. He kept on lieing on this known doping doctor, for example the motivation to hire him and the continued lies about his tenure at Sky (it's a parody on the 500 tests mantra).
Someone who lies about these things has absolutely no place in this sport. Of course the UCI won't do anything and yes, I realize it's impossible to act under nonexistant rules. However the UCI and the UK union should indeed put some pressure on this continuing farce. An ethical warning?
Not quite right, but close:
1. Consiously hiring dodgy medical personel => ban from the sport. I explained earlier why I think medical personel can't be given a second chance.
2. Hire a rider who has a doping past (or hire him as staff) => Be transparent about this from the start and it should be ok. Dopers who also acted as big time pusher of course should not be pardoned (bye David Millar).
Note that if your medical staff is clean chances of rogue doping should be
very small. And if trouble happens, as long as your medical staff can show they truly went all the way (by showing monthly data on blood etc on the riders) you should be able to handle it.
=> The aim is to break the facilitating chain. Make it so that the staff has everything to loose if a rider is positive. It will really enforce more internal controls and better background checks. Currently the punishments go to the riders, which doesn't hurt the facilitators.
And yes the legality will be an issue, so here's my proposal (top of my hat)
Enforce the rules for 2013 (2014, ianal), so everyone can fire all the medical staff with even a whiff. => To soften the blow call a conference with all teams and major sponsors and explain why this will pay out in very positive exposure even though you might have to liquidate some contracts.
Force the national unions to do monthly audits of the medical data for new teams, sliding to three months after two years (to keep down cost). Again, explain to everyone involved that by cleaning the sport sponsors will return.
Note that I am absolutely convinced there are enough young doctors without a past who would love to serve on a team. Paramedical personel is even more available.
Oh and for sure, Dave can start afresh like everyone else when these rules are there, you can't arbitrarily enforce rules backdated. There's a difference in my opinion about him and what's legally possible
Meh, it's a bit from the hip, but something like this is imho the only thing that can work.
