Prisoner of war.... enemy combatant
Prisoners of war get released when there is no possibility of them rejoining the conflict. Call them what you like at G Bay, they are still prisoners of a war.
If many at G Bay were released back to their homeland(s), in time, most would make tracks back to wherever they can again join the fray.
So what do you do with them?
You can kill them (naughty and not allowed) or lock them up until such time they can do no harm
When will that be?????
I think they'd better get used to prison life. most of them are lucky to be alive in any event.
