Also prone positioning with a knee in between your should blades would worsen the effect of “wooden chest syndrome” because it’s already known that this type of restraint interferes with the mechanical bellows action of the diaphragm which can lead to positional restraint asphyxiation.
The prosecutors will have stacks of medical reports and medical expert witnesses on this, including the MPD manual which warns against prone positioning restraint.
Thank you for being the only other person, besides myself, for mentioning ‘positional restraint asphyxiation’.
This was being added to my department’s training curriculum back in 2010 to respond to a large number of deaths from handcuffed prone suspects.
