Key to the marketing ploy underpinning Florida's detention camp in the Everglades is the alligator, portrayed by Republican leaders as a blood-thirsty prison guard ready to attack anyone who escapes.

But data and news reports about the first month’s arrivals show the majority of Alligator Alcatraz’s detainees do not have U.S. criminal convictions.  President Donald Trump, federal officials and Florida Republicans touted the remote Everglades immigration detention centers — dubbed Alligator Alcatraz — as a place to detain people deemed the "worst of the worst.

Editor's note: The little-used airstrip in the Everglades that the state is using to build a detention center for immigrants, dubbed " Alligator Alcatraz ," is part of a storied history involving Palm Beach County at one point.

The remote facility in the Florida Everglades is expected to cost the state about $450 million annually to operate.

Hundreds of detainees held at Alligator Alcatraz, the immigration detention center in the Florida Everglades, do not have criminal records or charges pending against them in the U.S. -- despite President Donald Trump claiming the facility would hold “ the most vicious people on the planet .”

Some people detained at the facility have violent criminal histories. But data and news reports about the first month’s arrivals show the majority of Alligator Alcatraz’s detainees do not have U.S. criminal convictions.

Without permanent structures, electricity or running water, logistical headaches have emerged at “Alligator Alcatraz.”
