[Cap'n Crunch]

It is impossible to say “I can’t breath” if you don’t have air coming into and out of your lungs. I have choked many people who say “I can’t breath.” I have been choked and thought “I can’t breath.” That’s right, you can’t until the pressure is released.

Your point is moot. The only thing that matters is that a banned maneuver (choke-hold) was applied which led to him being unable to breathe and not only did he die, they stood around and nobody rendered aid. Unless everyone at the scene is charged & fired, the changes are high that it'll happen again. Fire & charge them all and it'll never repeat.
