In Orange Is the new Black, the prison is bought by a private company - MCC (later known as PolyCon).
There are numerous instances depicted whereby this privately-owned company makes decisions over the prisoners' freedom. For example, MCC employees decide to keep an inmate in prolonged segregation - where the decision is seemingly solely in the hands of the company management.
In another instance, the company decides to accept a new batch of prisoners - and in order to make room for them, ranks the top 25 existing prisoners for early release.
Intuitively this seems wrong. Surely a decision on early release/parole is a legal decision, taken by the parole board. Not at the whim of a profit-making company in order to fit in with their executives' plans.
How realistic is this, in American law? Is this purely artistic liberty taken by the scriptwriters; or could it be possible in reality?
