Tobin said he analyzed Floyd’s respiration as seen on body-camera video and explained that while fentanyl typically cuts the rate of respiration by 40 percent, Floyd’s breathing was “right around normal” just before he lost consciousness. Similarly, he said people with severe heart disease have very high respiratory rates.
So he used the fact that Floyd's rate of breathing was average as proof that it wasn't slowed by fentanyl and also that it wasn't raised by heart disease? Wouldn't those two things cancel each other out?
