In the interest of carrying out more of President Donald Trump’s promised mass deportations, officials in Florida this week started construction on a migrant detention facility they’re billing as “efficient” and “low-cost” – because mother nature will provide much of the security.

The detention center represents a new, expanded front in the harsh optics deployed to dissuade migrants from entering the United States.

Immigrant advocates said the move creates a whole new form of detention outside the scope of the federal government.
