WXIA-TV/11 live says the nurses didn't surrender their licenses until this September, after it sent The Georgia Board of Nursing a link to the video the nursing home fought three years to keep secret.
And now, it has been shared publicly.
The newly-released video includes the deposition in court on November 23, 2015.
The video was played to the courtroom as the family's lawyer Mike Prieto questioned former nursing supervisor Wanda Nuckles.
Before playing the video, Nuckles tells the court nurses were giving Dempsey CPR repeatedly until the emergency services arrived. As the video rolls, the courtroom sees that did not happen.
The video starts with Dempsey, a decorated soldier, repeatedly calling for help, saying he can't breathe. He also presses the call light, which flashes on at 4.35am. He then appears to start losing consciousness.
A nurse does not appear until 4.42am, at which point she readjusts the bed, turns off the call light, and leaves, as Dempsey struggles for air.
Prieto asks Nuckles if that is an acceptable period of time, to which she responds 'nope'. He asks if Dempsey appears to be gasping for air, to which she responds, 'yep'.
'How does it make you feel watching this video?' the lawyer asks. 'Sick,' Nuckles replies.
The video then cuts to 6.23pm, when Nuckles and another nurse enter the room. They fix his blanket and adjust his bed as Dempsey lies motionless.
Prieto says to Nuckles: 'Contrary to the way you testified previously, there's no one doing CPR, is there?' Nuckles replies: 'No.'
They watch on. Another nurse enters, and all three stand around the bed talking.
At 6.30pm, as they try unsuccessfully to restart the oxygen machine and Dempsey takes his final breaths, the three appear to be laughing - with one of the nurses doubled over laughing.
In the courtroom, Prieto stops the tape and asks Nuckles: 'Ma'am was there something funny happening at 6.30am on February 27, 2014 in the middle of this attempt to resuscitate Mr Dempsey?'
Nuckles replies: 'I have no clue sir, I have no clue. I can't even remember all that, as you can see.'
Prieto asks: 'Do you see any sense of urgency on the part of any of the medical providers here ma'am? Including yourself?'
Nuckles replies: 'I think I was doing pretty good considering I didn't have anything good to work with.'
Prieto says: 'Ok well when you testified earlier that you walked in and started giving CPR until the EMTs showed up, that wasn't really the truth was it?'
Nuckles replies: 'Sir that was an honest mistake because I was just basing everything on what I normally do.'
The video continues showing all nurses leaving, with Nuckles remaining. She adjusts his bed, and fixes a breathing machine onto Dempsey's face. She then performs six chest compressions then stops.
'Any reasons to stop after six chest compressions there ma'am?' Prieto asks.
'Not that I know of,' Nuckles says.
It is illegal in Georgia to install a hidden camera in a nursing home without prior consent from the nurses and the establishment. However, the revelations from the footage absolved Dempsey's family of charges.
Speaking to
Channel 2, Tim Dempsey said he had assumed his father's suspicions were over-the-top.
'We would have just thought it was natural causes and everything was done that should have been done and he passed away in his sleep,' Tim Dempsey told Channel 2's Rachel Stockman.
