This is how Tyler Hamilton describes the Omertà in his book
The Secret Race:
The Secret Race said:
It's funny - you ofter hear about cycling's omertà, which is real enough. But when you're inside, it's positively chatty. Riders are constantly talking, whispering, comparing notes. The rewards were too big, the punishments too mild, so the hunt for the next magical product was too tempting. The peloton was Facebook on wheels - and during this period, information was flying.
So everything was well-known
within the Peloton, but the information didn't leak out and practically everyone kept their mouth shut when communicating with "others". While this type culture could've been widespread until the end of the Armstrong-era, there were two reasons why the sport was different then:
1) Law agencies weren't mostly interested in investigating the doping issues at all and correspondigly the legal issues were minor and the risk of having to testify under oath (perjury?) about doping practices of other cyclists was negligible.
2) You actually had to test positive or have been found having PEDs in your possession in order to get any disciplinary measures directed against you. The tradition has slowly but definitely migrated towards accepting other evidence than AAFs as evidence of doping use.
My reading of the situation is that the secrecy is there but the open discussion is gone for good. I wouldn't be surprised if the use of doping methods of individual cyclists is kept secret even from their teammates.
It should be emphasized also that "silence" as such doen't mean neither that the "silence folks" know anything nor that there is anything to be silence about in the first place.
One example of faulty reading of the "silence" was when anti-doping activist Don Catlin visited the Netherlands to solve the mystery of the death cyclists which he and many other sincere people attributed to overdosing of rEPO. When he couldn't make their relatives to admit that the cyclists had taken rEPO, he just assumed that there was code of silence operating and started seeing secrecy everywhere. Maybe there was one, but I am not convinced myself.
It's like the video about the UFO-conspiracy guy getting hit by Buzz Aldrin, there is always a portion of population who find that as a proof that omertà operating within the astronauts.
