I got a detail wrong in the account I gave of Peter Watts' incarceration, in the post below. I had understood that he had been released from custody in Port Huron, wearing nothing but jeans and a denim shirt, during a snowstorm - then walked across the bridge to Canada.
In fact, officials in Port Huron did transport him back to Canada before leaving him there, coat-less and without a vehicle, in a winter storm.
Just learned this fact after talking with Peter again. I've sent the correction off to John Scalzi and Cory Doctorow. I have also posted it here.
