That isn't how investigations work.
They don't need to prove that step, they just need to be able to follow the connection which will surely lead them to stuff that they can prove. And there is always something that can be proven.

So every transaction can be traced to its origin. If I connect to the network through TOR and generate 50 BTC, and then buy some substance with it, it's very hard to trace that to me. But even if I bought coins at an exchange, and they, as required, have verified my identity, I can still do the following:
- create another wallet (possibly online, like instawallet)
- transfer some BTC to that wallet
- buy substance with that second wallet
- erase that second wallet
now I can always say in court that I paid some other guy for his service (drug withdrawal consultancy?) and that's him who later bought the substance. While obvious lie, can that be considered a proof beyond reasonable doubt that I indeed bought the substance?
