Even were the story true, both American and Canadian authorities would be at fault. About 25 years ago, I took the ferry from Bar Harbor, Maine to Yarmouth, Nova Scotia, Canada and back and recall minimal security on the part of border officials of either nation.
I don't remember when the issue was cleared up, but I remember hearing the (false)rumors after 9/11.
Ping also to Tony Snow, if you still lurk here. I hope you know the truth now, as I heard you on Rush once, (before becoming press sec.) giving out the same incorrect information.
