Nope, still not right. The team (farmer) would buy all the bikes that they said they bought. Nothing changes there. It's what they did with the bikes (tomatoes) when they got home that is the issue. That has nothing to do with how many tomatoes trek took to the market.
The team, the farmer, will then say they either no longer have records of what happened to all the bikes, or they sold them on. But that doesn't prove what they used the money for. Do you see? And this has nothing to do with federal funds either.
This is a total dead end. Old Columbo is going to be chasing lance around for a long time if this is all he has.
i doubt they are pursuing the bikes-for-doping angle either, but mainly because the bikes presumably became the property of the team the minute they were given to them, and so the team was free to do whatever they wished with them.
i agree that the misuse of federal funds issue is also pretty tenuous, but for a different reason--the united state postal service is not a federal agency, it is a quasi-governmental, private corporation with a federally sanctioned monopoly. funds from the USPS are not governmental funds. also, like the bikes above, the money paid to the team would become the team's property as soon as it was transferred, and they were likewise free to do what they wanted to with it.
regarding culpability for tax payer funds paid from USPS to the team, which was subsequently used in an illegal manner by the team, responsibility would lie, if at all, with USPS itself failing to conduct due diligence and proper audits etc. but even then it is a pretty weak argument: if you work for the government and you use part of your salary to buy drugs and child pornography, and your boss knows you do this, neither you, nor your boss, is guility of misuse of public funds--the funds stopped being public when they were given to you as your salary. classic misuse of public funds is when you have access to a government expense account and are paying for your private expenses directly from the government's account.
trek is probably being subpoenaed because they have a long business history with lance and a long history of colluding with him in inappropriate ways (see the greg lemond case). prosecutors cast as big a net as their funding and staff allows--the bigger the net, the better the chance of finding something that sticks.
it isn't clear to me how money laundering is an issue in this case. money laundering is a way to account for excess cash in one's bank account that can't be explained by one's income. trek presumably gave the bikes, real or other wise, to the team. they didn't sell them to the team. so there is no money laundering there. if the team then sold the bikes and bought PEDs with the proceeds--that's just a straight up transaction: grandma gives you an ugly sweater for christmas, you sell it for whatever you can get for it. no money laundering has occurred, you've just sold something you own.
how to launder money:
The solution--classic money laundering--is to create a business to ostensibly earn that money. Any business that brings in a good deal of cash will do. You run the business as usual during the day. Then, after closing, you feed in your day's illicit receipts, pretending that they'd been received by the business. In due course the business pays its taxes and all the tax man can see is that you're running an unusually profitable business.
Now, the tax man may well take an interest in such a profitable business, so it's best if it'd be hard to prove that you couldn't be doing the business you're paying taxes on. A bar, for example, wouldn't be the best choice, because you wouldn't have ordered enough booze to pour all the drinks your books will say you've sold. Coin operated laundries and car washes are classics, because the only way to prove that you hadn't actually done all that business would be to have an undercover agent surveil your place for weeks, counting every coin inserted by every customer. (Although agents have been known to subpoena the water bill and try to make the case that way.)
