lots of things
First, even if its not illegal-which Im sure it is on some level-I would still say its wrong to cheat in sport, and all those people he cheated against are victims. They engaged in what was presumably a fair contest. If any others cheated then they have also committed a crime. Just because someone has committed a crime doesn't mean that they cant also be a victim. One might even say that they were forced into cheating after Armstrong brought doping back big time in 1999. So there is the cheating itself, and the others in the race, and the people there or watching on TV who believed the race was fair. When someone lies it is not the fault of the person who believes the lie. Blaming the victim does not excuse the crime.
So then you got all the legal shenanigans. Perjury, which is a crime against the justice system, state, etc..etc.. Witness tampering. Just because these are not directly "crimes against property" directly does not diminish their significance.
In fact they have been important in perpetuating what I think is the greatest crime of all; coercion affecting the "property" of millions of people who bought the livestrong myth, literally and figuratively. "What am I on, I'm on my Bike." Shameless, terrible lie.
I think its awful that in our society we excuse lies like these because they aren't "crimes against property." It's somehow ok to lie to someone about the very nature of who you are if it will help you get the sale. It is somehow their fault they believed you. Liggett, Sherwen, Roll, HV, JB, all are complicit in this big lie, which they justify by personal financial gain. Everyone is mad at Floyd about the fairness fund, a fraud for sure, but what about the 100 million LA has put away by virtue of his lies. Where do you think that money came from? people who believed his BS.
Not to mention all the trolls on this forum that I have been victimized by, criminals all.
