The lawyers are not stupid. They did their homework and any false statement came out from witness will be turned against the opposition. At least the witness will be disqualified. So don't need to act smarter than professional. Everything has black and white and it is traceable. Even someone use burlap bag to bring cash to bank, sure the bank has their ID record and also CCTV record.

If money laundry is so simple, no one need to open up RM2 company to wash the money. Just bank in cash will do.
