Our Coast Guard should have done the same thing when Castro emptied out his jails and sent them toward the U.S. in small boats.
But you know how that goes. The quote by the Statue of Liberty reads,
"Give me your tired, your poor, Your huddled masses yearning to breathe free; The wretched refuse of your teeming shore, Send these, the homeless, Tempest-tossed to me"
That says it all. And Fidel took the opportunity to empty his jails. ;)
