Yes, I've actually seen the full video, which you didn't provide here.
The grunting sounds do not equal distress. When a person is dying they get what is called the death rattle. It does not cause them any distress but is distressing to witness. Same with agonal breathing. There is nothing to suggest he was distressed just because there were grunting sounds.
A recent video of sn on here the woman made grunting sounds. This went on for quite some time. She also fell face first into her bed. Struggled to get up to vomit. And went through quite a lengthy, unpleasant looking experience.
Mr. Marin, on the other hand, was able to accomplish his final exit in a packed courtroom, without a lengthy protocol, and managed to turn and look at his loved ones one last time before passing. This all happened in the span of about eight minutes. Much more peaceful looking to me and much quicker than sn with fewer requirements.
It seems the full length video has been scrubbed, unfortunately.
