Not only can I prove where my $25k came from, I am prove when I bought the coins, and when I transferred them to BTC-e. If your a money launderer and you had stolen BTC, then yeah our really don't have a leg to stand on and should probably just throw in the towel.
So hire a good lawyer to have your money back, I'm not a lawyer, but I believe that in these cases you have the right to get your money back because you have nothing to do with the crimes of the owner of the exchange
I only had cents in btc-e, so I will not bother recovering the cents
