I can't say who is right and who is wrong in this LR stuff, but the legal system is working as it was designed.
Not at all. You seem to forget the definition of money laundering you pointed out? You don't have any evidence of illegal money because their source is concealed. To have any evidence of money being illegal you have to know the source. Simple as that.
Your arguments are the same the Holy Inquisition used during the dark ages. Inquisition agents selected their targets on "probable cause" based on "some evidence". During the interrogation the "defendant" has to prove he/she is law-abiding citizen and that he/she is not guilty. If the poor victim died during the "indictment process" this was the ultimate proof that they were guilty, because God won't allow innocent people to die.
I don't have any evidence of anything, and am not involved in the case in any way. The evidence was presented to the judge who processed the warrants. If this is anything like most criminal cases, the evidence has been piling up for a long while and they don't pull the trigger on prosecuting until they are pretty sure they have what they need, or they aren't likely to get anything better by waiting.
And yes, modern law is based on some pretty archaic and ancient principles, though the frequency that they blame god for things since the inquisition has decreased.
To be clear, you are arguing against someone who is a strong advocate of 4th amendment protections, and is more or less on your side. All I have been doing is explaining the process. It is not so unusual.
As to what evidence the prosecution might have there are all sorts of possibilities irrespective of where any particular transfer originated. According to the public reports, this was the combined effort of 17 countries. For AML, usually it is some criminal that gets caught on something more serious that cooperates with their local authorities and explain to them their process. Sometimes they get a lower penalty when the give the state evidence against others. The electronic transfer record is not the only evidence that can exist, so even if you are acting anonymously digitally, you may not be anonymous in other ways.
