Wasn't it just recently that a handful of terrorists escaped from a French prison? Pound sand is right!
There was a mass escape from a prison in Yemen, but no escape from a French prison that I can recall.
Not long ago Germany released a terrorist who killed an American after the bad guy was in prison about 7 years -- the Germans said he fully served his "life" sentence. The same thing would happen in France if we give back Moussaoui.
