Them is a response to American immigration policy under the Trump administration. The twelve-cage wall formed from livestock fencing isolates a small bell at its center. The cages are held together with zip ties similar to those used by border patrol for restraints.
When we as a culture look at our neighbors as “them” or “those people” we turn them into something less than human (thugs, drug dealers, rapists) making it possible for children to be separated from parents and detained in inhuman conditions. This is nothing short of state sponsored terrorism.
