I remember Roche being spat at throughout the 1987 Giro. Not due to drugs at that stage, but because he was as good as their local heroes. The American riders were hated, not helped by LeMond beating French luvvie Fignon on the final day's time trial in the Tour in 1989.
Great post.
And with many British punters always hating the successful, a hatful of forums posters made it plain they wanted Froome and Brailsford crushed. Tried, convicted and sentenced by the Court of no-privy-information Public Opinion.
During the Tour de France, the French police can raid teams, arrest staff and riders, and charge them whatever their nationality.
With the deterrent you mention, do you think the Tour is clean now from EPO and illegal drugs? (A genuine, non-retorical, question).
French legends Jalabert and Virenque were caught high level doping, including a failed EPO test.
Did they have their titles and category winning jerseys scrubbed from the record books? No.
There's always been a very special interest in investigating English-speaking riders, the 'interlopers'...
