I would. Well not against the individual athletes but against their country of origin. Countries screening would need to be better than the IOC ones or en par.
The basic framing is: “your boss fucked up, you’re part of the fallout”.
An alternative would be to allow all doping.
But at the moment the approach is to reward the smartest cheaters and at least for me removed all interest for most sport events.
That is a very good point which I haven’t considered!
Thanks :)
