I think both work. Unfortunately.
I normally don't watch these types of videos, but I forced myself to watch this. It's not right that I shouldn't. I imagine its me in the drivers seat and my son in the back seat. The horror. That poor child saw his father slain. I can't imagine. For every one of these such videos there must be thousands of others, also dehumanizing, but wherein nobody dies and there are no cameras around.
edit: I'm so sheltered. My first thought was "how could she be so calm and filming this?" Then it occurred to me that this image, this event is so foreign to me that I'm shocked in a way that perhaps she isn't because this is NOT foreign to her. This is a part of her existence. Her child consoling her in the car "I'm here with you." Dammit, if that doesn't get to you, you are a monster.
This is awful stuff. Appalling stuff.
