I remember Constable Sonnenberg's death as a kid, we had just moved down south and we passed that spot on Deerfoot all the time. It always made me sad seeing his memorial there driving by it as a passenger or a driver. I know they've moved it now.
I think it was his family (sister?) that pushed for Calgary Police to get HAWCs in the first place wasn't it? It's been so long ago now.
EDIT:
The police did what they could without making it worse. No win scenario. Didn't chase him just followed. The waste of skin was always going to kill somebody going at those speeds and running red lights along a core street in the middle of city. Just a matter of who was just happened to be unlucky and in the way.
