Cite the policy. Please, cite the exact policy.
The real policy is, that officers will not obstruct the airway - that is they won't "choke" people. The hold used by the officer in question did not obstruct the airway. There was no "choking" taking place.
Some fat slob resisted arrest, he was taken down to the ground so that he could be cuffed, and his medical problems killed him. The cop didn't kill that fat man, his own medical conditions coupled with his unwillingness to cooperate with police killed him.
I am not arguing semantics here, not at all. There is a very definite meaning of "choke hold". No choke hold was used here.
Talk to any wrestler, talk to any martial arts expert, talk to any cop. Get any of those individuals whom you have trust in to demonstrate the difference between a choke hold, and any number of other holds.
A reasonably healthy person can be held all day long in any hold which is not a choke hold, and he may suffer some pain, but his life will NOT be in jeopardy.
A choke hold, by definition, is a life threatening hold, which WILL kill the healthiest of men within minutes.
Semantics my ass.
