"This" being a certain victim impact statement quoted in the story. Mr Robert Waikari, a munter, persuaded a young acquaintance, Ms Tini Christy, to drive his unroadworthy van that couldn't move in a straight line, because she was less pissed than he was. The resulting crash killed him.
In a display of the level of wisdom and personal insight that tells us how Waikari grew to be the munter he was, his mother felt inclined to get up in court and read out to the young girl whose life Waikari had ruined a "victim impact statement" - the mother, presumably, being somehow a "victim" in this (or at least, a "victim" of something other than her son's stupidity).
I don't think I could have sat through it without offering Waikari's mother a few suggestions as to where she should be looking if she's determined to blame someone.
