A get-away car.
So one way to do the job is to make obvious and not so obvious errors, make it look like incompetence.
Privateers and their off-shore Carribean treasure troves..... The Panama Papers, a Rizla (tm) of what exists today.
The original privateers were a much earlier version of 'outsourced military capability' on behalf of the State. The East India Company also operated as a Legislative, and as a form of Governance, which provided the infrastructure to bring resources to factories and goods to market, as well as supply lines for military operations. Cue G4S being suggested as a back up police force...
If you know your history. Outsourcing military capability and resource capture.
