From your that link you posted:
“The record number of deportations comes even as 580,946 young unauthorized immigrants have received relief from deportation and work permits since 2012 under a policy called Deferred Action for Childhood Arrivals”.
In addition, those numbers which fooled you, included those who never even gained entry and were turned away at points of points.
You got hoodwinked by corrupt .gov
Er, points of entry
