Ok. I did. The origins of the Rikers are ok, but the question of sustainability remains. It's really unrealistic that the US Army just doesn't step in. Also, there's 9 000 officers tending to them (wikipedia), I think a riot of this size would be unlikely (I can give this one a pass on the account of the virus). Also, there's about 10 000 prisoners in Rikers, not all of which are murderous psychopaths, not all of which are trained in using weapons and not all of which would really like to organize or go on a rampage. Saying otherwise is simplistic and not realistic at all.
I know this is 'nitpicking', I don't mind any of this at all per se. But it's 'grounded' only in as such as it has no outright fantasy/sf elements, not in a sense that 'this actually depicts the way this type of situation would go down'. If you ignore the fantastical elements of, say, Destiny, it's set-up (aliens preying on the carcass of human civilization) is more plausible than a few thousands of poorly trained convicts wanting to take over NC and being more than a match for the US Army.
