Ping to Neighborhood Fortress
Give the encampment a patriotic name, throw some patriotic words and phrasing out there and under that guise they will soon have real Americans paying their own way to be locked up in indoctrination camps. Walk right this way folks and your troubles will be over!
It's got all the things that an indoctrination camp would need. Multi walls (to keep you in after you're already there), residents continually under the watchful eyes of those on the walls, food distribution site (seeing that there is no where in their plans for farming activities or cattle holds), and the list can just keep going on for a long time.
To me, this looks more to keep people in rather than out.
