So someone explain to me how he's not facing any charges at all?
I've seen countless documentaries about people in prison and watched plenty of shows like The First 48 where someone goes to jail for life, even if they didn't actually do anything, but were physically present when someone in their party killed someone else.
If that person truly had no knowledge that their friend had a weapon and was planning on killing someone, then I always felt that this sort of punishment was unfair, but that's besides the point.
I just can't ever recall that defense ever letting somebody completely off so how is it that he's not facing any charges at all?
