Arpaio is a living caricature of practical racism. I know people who are hardline crazy OBAMA (racial slur here) FAKED THE MOON LANDING kind of people who are repulsed by Arpaio.
There's no way he'll pardon him. I hope there's no way he'll pardon him.
Him and Trump's beliefs are very similar. They both fail to properly distinguish between latino citizens and illegal immigrants. And they both support policies that would make illegal immigrants into long-term second class citizens. Joe being worse (on this one issue) because the policies he supported would turn all latinos into second class citizens, constantly having to live in fear of deportation.
Edit: I wouldn't call him a caricature. He's more like, okay you know those countries that used to be colonies and the imperialists left a minority ruling over either a majority or several other minorities that are together the majority? Like Iraq. He's what a Sunni cop in Iraq would be in the Kurd or Shia areas. Its just that we aren't used to that in the US, except in the context of African Americans, but we've been explaining that away for decades. A typical person, but not in a typical place.
Double Edit: This is under Saddam Hussein to be clear. I have no idea what if any law enforcement is going on in Iraq at the moment.
