This was an OK episode, not my favorite.
I don't like Duncan killing an unarmed woman for any reason, like was said earlier he could of stabbed her or chopped off the hand.
Does bring up a good topic though; yes the white supremacist may of been bad, with evil thoughts. But is that alone reason enough to kill them? I think not.
You should be judged by your actions & not your thoughts; this applies to so called hate crimes.
If you commit a crime you should be punished; saying that it was a hate crime is belittling the other victims of the same thing.
