Why defend Joe Papp?
If only half of what is reported is correct, anyone hoping for an explanation that justifies Joe's actions is headed for disappointment IMO*. However, I wish Joe well and continue to give him the benefit of the doubt wherever I can,
because he spilled the beans. I consciously try to treat riders who name their suppliers differently to those who don't. Choosing to respond differently to riders who behave differently is not a double standard.
From the information available so far, I believe Joe's actions were at least partly motivated by self interest. However, it's entirely possible that he was also motivated by wanting to atone for his crimes. That's one of the areas that I can still give him the benefit of the doubt. I don't see any problem with someone acting partly in self interest, as long as they don't act entirely in self interest. In fact, capable adults who fail to look after themselves are just a burden for whoever gets to pick up the pieces.
There is also reason to believe he wouldn't have become a drug trafficker if he wasn't exposed to the doping culture in cycling (and the endless 'you have to dope to win' marketing from the likes of BigBoat

.) So, there's reason to believe that he might change his mind about doping, after being forced to stop riding and face the consequences. Perhaps he
now genuinely wants to discourage others from doping; I still give him the benefit of the doubt about that too.
For any of you who are directly involved with CLEAN competitive cycling, please don't assume that I'm trying to persuade you to offer Joe support. I'm not. I don't think the attitude of 'he did the wrong thing and has to pay the price' is entirely unreasonable. Just trying to explain why I chose to defend him.
*Joe, I sincerely apologize if I have underestimated you.
