Trump exposed in hot mic moment planning further abuse of power

QUESTION:

What section of the U.S. Law makes those deportees eligible for life

sentences without possibility of parole?  Because, if there is no such

law, no such violation of any such law, then their confinement, as arranged

by the Trump Administation is cruel and unusual punishment.  If it shoud,

therefore, require U.S. Military action, there is no reason that it should not

be taken to arrest a criminal enterprise that is in contravention to U.S. Law.
