Officer in Garner death

* On the MSNBC Sunday show, Al Sharpton usually addresses racial-justice issues responsibly.  Not so when it came to Michael Brown’s death in Ferguson and Eric Garner’s death in New York.  In these cases he incited resentment of police unjustifiably, excessively and regrettably.  Regrettably because resentment leads to contempt hence to crimes and their sequelae.  Excessively because Sharpton kept provoking his audiences already riled.  Unjustifiably because the officers in these two cases were not guilty of wrong doing – the shooting of Michael Brown was provoked and defensive; the neck hold on Eric Garner was not the cause of death.
* Each of these victims was breaking the law.  Each was very large and resisted arrest.
* Michael Brown assaulted then threatened his arresting officer and was approaching him when shot.  It is proper for a lone cop to shoot before closing with an oncoming belligerent.  The witness lied about the event.
* Several officers were needed to subdue Garner, each trying to control an available part, including his neck.  The neck-hold did not cut off Garner’s airway as evidenced by his continued utterances.  Heart-failure patients experience a drowning sensation ("can't breathe") during and after exertion.  The sensation supports the reflex response to exercise, that being deeper and faster ventilation to support exertion.  The sensation is due to lactic acid and carbon dioxide in the blood coming from working muscles (this together with diminished blood oxygen).  Another response supporting exertion is faster and stronger heart beats, signaled by sympathetic nerves and secreted adrenalin.  Likely Garner’s damaged heart, unable to endure the extra work, experienced ventricular fibrillation, which is lethal.  That is an ordinary heart attack.  In the brief struggle, the sympathetic stimulation would have been due to mental excitement more than the metabolite changes.  His heart probably didn’t stop due to pressure on the neck artery (carotid body), since that would render him unconscious quickly and would be quickly reversible.  In any case, his death was accidental not intentional.  
* Therefore, the officers involved in these two deaths did not commit crimes and should not be punished or hated.
