Actually, we've secretly been extracting and repatriating our Acadians:
A Louisiana state senator has praised a Canadian search and rescue team. Senator Walter Boasso said a Vancouver-based team reached St. Bernard parish five days before the U.S. army got there. ...The suburb of 68,000 people was initially ignored by U.S. authorities who were scrambling to get aid to New Orleans. Boasso said floodwater in his parish is still 2.4 metres deep in some places. ...Boasso saved his praise for the Canadians and their quick work. "They were so glad to be here," he said. "They're still here. They are actually going door-to-door looking in the attics" for people to rescue.
