I'll assume that you know what the concepts of Letters of Marque and Privateers are, so I'll get straight to the idea...
If you are Allied with a controlling faction who is at war / civil war, they can offer you a Letter of Marque.
This waives bounties from crimes committed against their opposing faction in any system that the issuing faction controls, for the duration of that conflict only.
Plunder and spoils taken from enemy shipping can be handed in to the issuing faction's agents for cash and influence.
Finishing your game of bowls before tackling the enemy armada is entirely optional
