I just passed by this system, it's the only Alliance Prison Colony I've found so far and to my surprise there are no restricted goods.
In fact it's the only system I know of that has salvaged goods like Black Box and Prototype Tech under legal goods, the only thing it doesn't buy is Toxic Waste.
It's seems to be a bug too because if you look under the factions tab the controlling faction has no type, even though it should probably be Prison Guards.
So until FDev fixes it it's FFA, enjoy.
