...."Alligator Alcatraz" is set to be an incredibly expensive boondoggle, though not for the reasons one would guess. The claim is made that security will be by alligators, but when one looks at the site, there are clearly roads in and out, and it's not quite as swampy as Everglades National Park to the east. Plus, most deportees are low to moderate security.
So where does the expense come from? More or less because it's being built super quickly in a place not suitable to hasty building , really--involving tents (hard to insulate, vulnerable to hurricanes), generators, solar panels, and more. This is one of many times where politicians really ought to be reminded to consult the experts in building and accounting before they sign contracts.
