I can see letting the Cubans in who got here by converting a 1950s vintage pickup into a boat to cross to Florida and who had the gumption to make the trip, but 'poor' Haitians who managed to somehow get the money together to bring their brand of governmental corruption here? Not so much. It makes me wonder who is funding them.
As in all things, follow the money, because at the wallet, you will find motive.
