Jim,
There seems to be a great deal of confusion about mace type spray in Canada. At the Detroit crossing I had a Canadian border agent tell me my bear spray was illegal and I would have to turn around and go back. while in the process of turning around some other agents asked what I was doing and when I told them they wanted to know who told me I couldn't enter and then they shook their heads and waved me through.

I have nothing but pity on the poor man whose foolish actions cost the life of his son. I cannot begin to imagine how torturous each day, each waking moment, must be.
