"This officer will be punishing himself for the rest of his life over this tragedy."

Which does Tamir Rice absolutely no good.  He's still dead at age 12.  The cop involved had been FIRED from another PD for instability and incompetence, and REHIRED by Cleveland PD.  And he walked.  I'm sure most child-murderers would like the opportunity to 'punish themselves', as well.  When this is allowed, a LOT more children are likely to die.

Show me some ACCOUNTABILITY for any aspect of this child's needless death and then let's talk about it.  As long  as cops are not held ACCOUNTABLE to the same degree as the power they wield over the rest of us--literally the power of life and death--then I have to live with the fear that the next black child they gun down with impunity might be one of my grandchildren--Allah Forbid.

That is what those not subject to such very real threats seem unable (or unwilling) to objectively understand or appreciate.

However, I do appreciate your acknowledgment.
