Also interesting is the comment immediately after the article, which I quote below:
With all due respect, I feel I've been transported into the early 1990s before Dr. Donald Reay recanted under testimony his theory of positional asphyxia, that his research was improper, and positional asphyxia related to the maximally restrained subject whose airway is not compromised doesn't exist. There is no reason, per Dr. Gary Vilke, MD, a UCSD researcher and leading authority on Excited Delirium Syndrome deaths, states "There is no physiologic reason not to" in attempting to restrain subject through vascular neck restraints. Placing weight as officers are trained to do to control a subject until handcuffed presents no danger to a subject and is used hundreds of times per day across the nation without deaths except for those who have a propensity or condition leading them to die having nothing to do with the officers' restraints. Yes, officers are trained to take body weight off a handcuffed, still struggling subject. Yes, officers are trained to no longer attached a hobble restraint to the handcuffs of that still-struggling subject. Yes, officers are trained to place the still struggling maximally restrained subject on his/her side in a rescue position. The reason for these precautions is for civil liability and optics, not for practical reasons. This article sets back our efforts to get real information in the hands of officers and continues discredited and disproven ideas.
Try this one. It’s much lengthier and technical from 2004

Also, apparently Dr. Donald Reay disagrees with people who say he “recanted”.
