Arpaio was one of the few who actually enforced border laws. He did it in a controversial way but then again neglecting to enforce border laws is controversial. But liberals see his tactics and say OMG HES A WHITE SUPREMACIST OMG NAZI!! Arpaio may have profiled people of Hispanic descriptions but that in and of itself does warrant the need to a time machine to put him in the Nuremberg Trials. Also, pardoning a person of with unpopular and perhaps unfair tactics is not even as bad as pardoning mega criminals and terrorists as did Obama and Clinton.
