I disagree. The victim's history (drinking) has everything to do with the story. Shows motive & background. Just if he had history for assault, theft or whatever the case may be. It stated the basic who, what, where, & why of the story. Looks to me this cop had a few issues going on, probably hates drunk Natives. We hear that all the time, just another drunk Native. The cop is probably not Native, could be racial. He lied, doesn't have any remorse, he's tried to save his own ass. The drinking problem that goes on in the villages is a major issue. So much that many villages are dry. From the YDD's comments this makes me think there are more issues with this cop. This cop seems like a violent person w/ anger issues. He sounds like an ass who thinks because he's a cop he can do whatever he wants & abuses his position & power. 
BODY CAMERAS MUST BE MANDATORY FOR ALL COPS!!
Keeps everybody accountable & factual. Giving $175,000 to a drunk is a death sentence. Heartbreaking for his sister.
