It is true that Sagittarius A* has no authority governing it at the moment, so no laws to break, and no presence to enforce it.
Yet paradoxically, I feel it should need no enforcement by a single power, as given its currently understood role in the history of the Galaxy, it may well be the most significant single object in the galaxy. It should belong to everybody, a place for everybody to meet together and visit in peace, without permits, without prejudice, without malice.
Perhaps, with more people visiting the system now, it is time for the current human governments everywhere to recognise Sagittarius A* as a system in its own right and grant it Universal Protected Status due to its historical, natural and astronomical value? Specifically, in its role as neutral ground. It can then follow that any such attempts to defile the system with killings of innocent pilots result in a severe penalty: say, a prolonged Wanted period across ALL civilised human space?
Any thoughts? Something worthy of an official in-game petition?
