Novak on TV: Alex, I don't know if you can hear me. But tonight, you uncovered a nest of vipers inside the Detroit Police Department. And in so doing, you shed light on an invaluable truth. Even the police, the men and women who swore to keep us safe, they can be bribed. They can be bought. Machines, however, are corruption free. Americans could be living in a country where law enforcement is not only efficient, but incorruptible. Thank you, Alex, for all you've done. And for all that you are.
-- Robocop 2014
These are the lines uttered by Novak on TV. I wonder why could be living is used rather than could live. Any nuances suggested? Is be living the present tense embedded in the modal construction?
