It's not a matter of whether you like it or not--the officer has not been (and likely will not be) treated the same way anyone else would be treated if they negligently fired their weapon.
The reality is: he will almost certainly either not be sentenced or receive a reduced sentence due to his profession.
But that doesn't make this family any less violated.
It doesn't make a little girl any less traumatized.
Any time the police shoot man or beast negligently, it is a crime, not a mistake.
More likely, he will be treated as the officer who killed Aiyana Jones, as the officer who shot Dakota Corbitt----the child pays the price (with her life, in the former case; hospitalized in the latter). His own Sheriff may continue to defend him, as did the Sheriff in Georgia after his men were known to have thrown a live grenade in a baby's crib.
As soon as the outrage blows over, the officer will be back on the street. (It is known that the officer who killed Aiyana Jones was reinstated).
Then folks like you can go back to defending them, making excuses for them, and otherwise enabling the status quo.
How many more children will needlessly suffer or die before you stop making excuses, I wonder?
This can be stopped, even now. But it will require those who are content with the status quo to take an uncomfortable stance.
