Just scale the bounty on a player's head, to the skill/type/number of NPC system force that will intercept and interdict him in the system where he is wanted, accordingly.
A player with a high notoriety and bounty should be constantly interdicted by 3 wings of Elite, engineered Anacondas and Corvettes armed with Guardian weaponry.
I mean it only makes sense for a guy high on the FBI wanted list to have every cop in town, along with SWAT and their mothers' pet chihuahuas, on this tail if he is spotted, right?
