this i agree its paper how can that be traced 4 drugs and laundering..
Of course it's trivial to launder cash effectively.
But some form if tracking might still be implemented:
- Peter goes to ATM and enters card and pin.
- An OCR system reads the bills serial numbers, Peters ID is associated with them in the database.
- Peter buys some illegal item from Jane.
- Jane gets busted and her cash ends up in the hands of forensics.
- Forensics query database for bills withdrawer IDs.
Of course if Peter bought a hotdog and the hotdog vendor bought from Jane then the tracking is broken.
But still some positional information will always remain and will give a little more insight into Jane's operation.
Also, if Jane's cash contains many bills associated with Peter then that would raise a red flag.
