Kai was outraged by the conviction of Dr Peter Watts, the Canadian science fiction writer who got out of his vehicle while crossing back into Canada to ask a US border guard why his car was being searched, and was clubbed, gassed, charged with a felony, and left in wet clothes in an unheated cell overnight during a snow-storm. So Kai made this sign warning unwary travellers of what they might expect the next time they cross into Canada at Port Huron. I've checked with Peter (who is awaiting sentencing) and he's OK with this being posted.
