Yep, it's a bit complicated.now that is a good explanation.
I just assume that 'assassinations' can't be done in public. That's frowned on even for state players. If I want head of nation X dead, I can't just have my agents walk up with orders in hand and shoot him in public. Either that's done secretly, or I make up a military operation such that his death is just part of that operation.
So I kill the target quietly, in an isolated area and whistle on my way back to the ship I even parked on their pad =D. Unless it's not covert and I need manufacturing instructions. Then some other dead people are likely going to be decorating dark corners.
